I'm pretty sure I'd make the teacher cry.

I don't understand what's wrong with this question. I think the student answered the question wrong, yet my friend insists the student got the question right.

I feel like I'm missing something critical here. What am I thinking wrong?

Sarcasm overload.  Must get a beer.

Oh man... when I was in high school physics the teacher asked a question like:

A car linearlly accelerates from 10m/s to 20m/s over 10s.  How far did it go?  (Or a rocket, or whatever).
Her answer: 50m
My answer: 150m

I "got it wrong"

How did you get it wrong?  There are formula that are literally single equations for that sort of shit.  Multiple choice?

No, free form test.  She somehow thought that the base 10 m/s could be discarded.  And treated the problem as accelerating me 0m/s to 10m/s.

Me: Well, a vehicle going 10m/s over 10s would go 100m.  Yet this one was going faster, but didnt go as far?
Her: That's an entirely different problem.

I would have responded with, "Ok, let's test this theory of yours."  Then I would have found the nearest calculus textbook and thrown it directly at her.

Well, I was in 10th grade, I didn't know calculus yet... but, like Thib's formula, it's a square plus a triangle.
