The two wheels are connected by a belt. The diameter of one of them is 2.5 times the diameter of the other. A small wheel makes 100 revolutions per minute. How many revolutions per minute does a large wheel make?
Since the wheels are connected by a belt, the same length of the belt runs along the outer rim of each of them.
The diameter of a wheel is directly proportional to its circumference.
This means that if the diameter of one of the wheels is 2.5 times the diameter of the second wheel, then it should make 2.5 times less revolutions per minute:
100 / 2.5 = 40 (rpm).
Answer: The big wheel makes 40 rpm.
