What is a proportion?

A proportion is a fraction of a total amount, and is solved using a rule of three.

In this problem, the amount of time is proportional to the amount of points the problem is worth. Hence, for a 5-point problem, in a 75-minute time, the time is given by:

t = 75/5 = 15 minutes.
