Question

A car’s wheel is rotating at 350 rotations per minute. If the radius of the wheel is 17 inches, find the speed of the car in feet/minutes to the nearest feet.

Answer 1

"A car’s wheel is rotating at 350 rotations per minute. If the radius of the wheel is 17 inches, find the speed of the car in feet/minutes to the nearest feet."

C = 2Πr

350 rev/min * ( 2 * 3.14159 * 17 in / rev ) * 1 ft / 12 in = 3115.413 ft/min

3115 ft/min

Answer 2

The circumference of the wheel is 2 * PI * r = 106.76 inches, which equals 8.897 feet

In one rotation the car will travel the circumference of the wheel.

In 350 rotations it will travel 8.897 * 350 feet ~ 3114 feet.

So in one minute it travels 3114 feet, so speed is 3114/feet minute
