Oh thank god, so I was solving it right. I got 9:34 and some seconds.
>>
>>148185447
What even is the right way to solve it? Algebra? I kind of brute forced it by narrowing it down between 30 and 40. Did some more work but I got 32 this time. 32x3/2=48 so it adds up nicely to 80.

>>148185657
Here's how I did it, cause now I feel stupid.
x=Time for one trip
return trip is 2/3's speed so I reasoned it out to x+(x/3)
80=x+x+x/3
80=(3x+3x+x)/3
240=3x+3x+x
240=7x
34.whatever=x

Never, because there are no parks in Gensokyo.

I'm not good at math:
So she spent 80 minutes jogging total.
Her total speed would be 5/3. So if I remember the operations, since it'd be 80 = 5/3 (x), you'd have to multiply 80 by 3 and divided it by 5, meaning x = 48, so 2/3 of that would be 32.

So she arrived at the park at 9:48, waited for an hour, left at 10:48 on the dot somehow, and arrived back home at 11:20.

most of /a/ can't solve this shit and I find that hilarious

Sounds correct

>>148186392
This is what I got too, mathanons pls verify.

>>148186392
Thank you. Now to never watch Ro-Kyu-Bu again.
>>
>>148186392
Your method is the most correct so far, but you've got the speeds mixed up. She gets to the park faster than she returns, so the trip there should take 32 min and the trip back 48 mins.

Who gives a shit at what time some dumb slut reached the park? Math is fucking dumb.
>>
>>148186643
Ah, you're right. Forgive me, its 1AM; I think I'm allowed a dumb mistake at 1AM
>>
>>148183975
>What time did she reach the park?
80min times 5 divided by 3.
>>
>>148186948
Sorry, that's just time it takes in minutes. So add that to the starting time. Silly mistake.
>>
>>148183975
at time I raped her

fuck you I'm going to solve it
a+b=80
D/v=a
(D/v)*(3/2)=b
a*(3/2)=b
a+a(3/2)=80
a=(80/5)*2
a=32,b=48
answer 9:32
