Didn't use math other than simply addition and subtraction in 20 years. I honestly don't remember how. I probably could work it out somehow but I don't feel like it so I came here.
Problem:
Going /out/ in a few days and decided to take some milk powder with me. It needs to be mixed with hot water (50°C-60°C) but not boiling hot. Can't measure anything other than seeing the water actually boiling.
With how much cold water (10°C-18°C) and how much boiling water needs to be mixed to get the desired temperature for the milk powder?
How long does it take for a "steel cup" (500ml) of boiling water to cool down to milk powder mixing temperature if the ambience is 21°C?
How do the results of those question change when it's done 1000m above sea level?

\u gotta include wind,time,ur stupidity and some other things too

Thanks for the laugh.
I bet you finished high school as well. This is why we radically need to change the school system and cut off people like this.

>wind, time
Isn't needed for the first question, you can ignore those. For the second question the result is obviously time so it's for you say and if you want to include wind let's say it windprotected or up to slightly windy.
My stupidity isn't a constant so let's ignore it there too.

you just don't know how to calculate it. at least I'm not pretending.
