We actually had questions like that on our math tests. Our teacher called them "the idiot questions" because idiots would try to calculate it and get it wrong.

T = 40P / P
The real trick is handling P = 0 which should return undefined.

P doesn't need to be handled, since P/P=1 and 40*1=40. And, in any amount of people t=40min.

0/0 isn't 1, it's undefined. That's the only case where you need to consider P since 0 people playing the music will take an undefined amount of time.

Which is why you don't use P=0 before manipulating the equation.

That would simply equate to T = 40. The equation looks more like this: T = (40/120)P
YangXiaoLong · Verified · 2 points · 6 years ago
Equating t to 40 is exactly how it should be, it's the equation associated to the problem, since t is not a function of P.
EmilG · 3-Year Club · 2 points · 6 years ago
In the real world, yes, but it is implied by the question that T is a function of P
