The diameter of a bicycle wheel is 60 cm. How far will the cyclist travel if the wheel makes 5 revolutions.

To solve this problem, we introduce the conditional variable “X”, through which we denote the distance that the cyclist will travel if the wheel makes five revolutions. Let us apply the following formula to solve the problem: S = 2 x n x D / 2. Then, based on the data of the problem, we will compose the following equation: X = 2 x 3.14 x 60 / 2. Solving this equation, we obtain X equal to 188, 4 centimeters.
Answer: If the wheel makes five revolutions, then the cyclist will travel 188.4 centimeters.
