What did she mean by this?

What kind of garbage broken english question is this?

Sawing a board into 2 pieces is 1 cut in the middle.
10 minutes to make 1 cut.
Sawing another board into 3 pieces is 2 cuts
2 cuts, 10 mins each = 20 mins

Get out of 7th grade ffs OP

Your teacher is retarded

>>719156165
she means she is an idiot and you should let her know 1 cut = 2 pieces
2 cuts = 3 or 4 pieces

>>719156165
I think she's trying to break your will Orwellian style. You must be a cis white male. Check your privilege. Obey. Obey. 2+2=5

>>719156524
>she means she is an idiot

Ironically, the field of education attracts the lower end of the IQ spectrum.

Sawing a board into 2 pieces takes 10 minutes, divide that and you get 5 each. She added another 5, which is how long it'd take. So it's 15.

you're supposed to assume that Marie's time is cut in half with each cut, obviously. Duh.

A cut takes 10 mins. Another cut would take another 10 mins. This is not an algebraic question, this is a logic question.

>>719156639
Approve this.
You all asume it is about cuts, but there is nothing given about cuts in the question, it is about the pieces.
Learn to read

It would take Marie 5 minutes to saw a board into one piece

>>719156165
what the fuck is your teacher even doing at your school

Public education is fucked here in America. Teachers are too lazy to make sure the fucking questions they are writing are clear to read and understand.

10 ÷ 2 x 3
= 10 ÷ 6
= 60

i don't get what the big deal is here

>>719156639
The produce two boards, she made one cut at 10mins. To produce three boards, she needs to make two cuts at 10mins a piece. The answer is 20mins and anons teacher is an idiot.

>>719156746
But in america. Humpty buttfuck mc cherry cheese nacho monkey steamroller meatloaf durkadurkadurka weeeeewoooooweeeeewooooooweeeeeewooooooo NIGGERS!

See, the question is ambiguous. If the question was "how long would the cutting take" it would be 20 minutes. If it was how much time would each piece take, it would be 15 minutes.

>>719156165
>soak the board in water
>fold in half
>saw (since it's thicker, it takes ~5 minutes longer than usual)
>15 minutes

teacher is a genius

>>719156829
Mind blown.

2 cuts can be made in 10 minutes, leading to the conclusion that 1 cut = 5 minutes

3 pieces of woods = 3 cuts = 15 minutes

Simple. Only autists trip over this kind of questions.

The logical way to have 15 be valid is thus: The effort and technique is the same but the dimensions of the board, the cut, and the pieces are different. Say, she cut one board lengthwise. 10 minutes for 1 cut. Then with some completely different board, she cut it to the horizontal, 15 min. We could even get into different consistencies in the grain, hitting a knot, etc. This is truly a 3 star question.

>>719157018
I love this

American education in a nutshell.
Even the teachers are dipshit retarded

>>719156165

But real talk, if this is actually applicable to OP. You should talk to your teacher as both points of view are technically valid but yours is more useful in real life. As far as I know.

10 minutes per cut...

Takes two cuts to make 3 pieces.

Teacher is wrong. It's 20 minutes.

Go above teachers head

bait, pasta, etc

>>719157265
Correct but it doesnt state you would be cutting in that way

>>719157326
It doesn't state HOW you would cut it either

So it takes you 2 cuts to turn 1 piece of wood into 2 pieces of wood.

Youre complicating a simple yet poorly thought-out question. If she's sawing at the rate of 2 pieces every 10 minutes and you understand basic maths then you realize shes sawing 4 pieces every 30 minutes (2+1=3) (take the 3 and add the 0 )

The answer would then be 30 minutes

Please stop confusing everyone here who are looking for the correct answer

>>719156165
She marked it wrong because you didnt write your formula you fucking pre-calc wrong assholee
Let P : pieces

Let m : minutes

Let C : cuts

Let t : time per slice = 10

C(m)=m/t,{m|m<Life(Marie)},{C<length(board)}

P(C(m))=floor(C(m))+1,{m|m<Life(Marie)}


P(C(20))=floor(C(20))+1=floor(20/10)+1=floor(2)+1=2+1=3 pieces

Because where in the adult world, where this shit matters, is an attached diagram unrelated to the instructions?

I mean, seriously, consider for a moment that you're given instructions on how to put a wardrobe together. But as it turns out, the diagram provided is for a nightstand instead. And you'd be even worse off if this was IKEA instructions.

If the diagram is not indicative of the relevant problem, it should not be present, It is purposefully misleading, and would be cause for complaint anywhere else.

Meaning, there is nothing left of the board itself, it is now in two pieces, therefore it was cut in half. That's a teacher who doesn't write nor read their own tests.

There's a picture next to the question

>>719158236
I doubt this math question was aimed at adults, though. For all I know the picture is there because it has something to do with sawing. In the end it's just a silly math question that people can interpret in different ways.

>>719158330
No, I don't assume anything if there is no reason to, I'm also not the type of retard to put words into someone's mouth or get worked up over nothing.

Hmm I'm a teacher and I think it's more teachers are overworked and don't read the question, literally look at your answer and the answer booklet and write tick or cross.and copy the answer from the answer booklet.

Teachers are lazy, stupid, and entitled beyond any normal persons ability to comprehend. I do IT work for a new york suburban school district and it's taken 7 years to wrap my head around the full width and breadth of their stupidity and arrogance. Good teachers account for 1 in 10.

>>719156165

youre def right, as its 10 minutes per cut, not 5 minutes per piece. tell her that shit man, you are 100% in the right

1 cut yields 2 pieces of wood. Likewise, 2 cuts yields 3 pieces of wood.

yall are fucking idiots. Everone knows that after you use a saw to cut one piece of wood, the blade is hotter from the friction, therefore it's easier to make the next cut.

>>719160369
The person who came up with this problem has never had to do any physical labor.

>>719156165
the teacher is assuming the original board is not included in the pieces that are being cut off. she thinks a cut in the original board produces one new piece, not including the other part of the cut board as a second piece. they then cut the original board again to produce a second piece. if those two cuts took ten minutes then each one is five minutes of cutting time. therefore, to produce a third piece from the original board one cut is made which adds five minutes to the previous ten minutes, hence her thinking it's fifteen.

this obviously isn't the intention of the question though; your teacher's an ass

>>719160888
no it doesn't.
for the second cut the saw is warm and gets through faster, also marie is an experienced sawer now and can saw at higher speeds.
so a cut of 3 times the length of the first cut needs just as long.

then the saw is dull and the sawdust blocks the teeth, so the shorter cut needs more time per length.

The answer is clearly 30 minutes. 10 for each of the two cuts and the other 10 for all the time she spends complaining about a splinter to her boyfriend and over exadurating the pain.

Write that and you'll get an A.

>>719156165
10/2 = 5 (The time/the amount = the productivity)
Therefore 5 x 3 = 15 (her productivity x the amount = the time)

No. They were full time. I worked over the summer at my college where there was a training type thing for math teachers, and what I witnessed was damn near unbelievable.

>>719162282
You'll maybe get an A- for this answer even if she doesn't dock you for spelling. The answer is 45 minutes. She does the first cut after nagging her boyfriend to do it for days before, gets a splinter and uses that event to spend 5 minutes bitching at him while he is watching football with his friends (he didnt even know she was cutting the fucking board). He laughs and calls her a pussy and she spends the next 29.5 minutes sulking and finding reasons to "clean" in ways that just happen to make her walk in front of the tv so he can see her depressed face.

Finally the boyfriend has enough and goes outside, sawing the board with the same saw in 30 sec.

10+5+29.5+.5=45

>>719156829
And 2.5 to saw it into disappearing.

yeah that sure sounds like they are overworked and not that they treat education of kids like a chore.

you're just making a reference to the fact that most teachers are just losers who were only comfortable in a classroom setting. maybe higher salaries would attract better people, but sooner or later good teachers will be able to have thousands of students at the same time so it doesn't matter yet. kids learn on the job anyway when they get older, school should just be for social development.

>>719162615
Easy. You stare at the board thinking how to saw it in to 1 piece. After 5 mins, you realize its already in one piece. 1 piece = 5 mins.

not enough details
how long it takes to saw depends entirely on how long the cuts are

do we assume the boards all have the same dimensions? do we assume the boards are being divided into equal pieces?

if yes to both, then the answer is 20
if input boards have same dimensions but output pieces don't have to be equal, the answer depends entirely on how the cuts are made (with 15 min as the shortest possible time)

Say your first cut cuts the board in half. Imagining a perfect square, you now have two rectangles. Cut one of the rectangles in half, making two squares. This cut should have been half the distance of the first cut. You now have three pieces in 15 minutes.
