A wheel with a radius of 60 cm makes 40 revolutions at some distance. What should be the radius of the wheel

A wheel with a radius of 60 cm makes 40 revolutions at some distance. What should be the radius of the wheel, which makes 48 revolutions at the same distance.

Decision:
To solve this problem, we introduce a conditional variable “X”, through which we denote the radius of the wheel, which makes 48 revolutions at a certain distance. In this example, there is an inverse proportional relationship. Then, based on the data of the problem, we will compose the following proportion: 60 centimeters relate to 40 revolutions, as 48 revolutions relate to X centimeters. Then, based on this proportion, we make the following equation: X = (48 x 40) / 60. Solving this equation, we get X equal to 32 centimeters.
Answer: 32 centimeters.
