Question

The diameter of each wheel of a bicycle is 26 inches if you’re traveling at a speed of 35 mph on his bicycle through how many revolutions per minute are the wheels turning

Answer 1

≈ 452.5 rpm

Explanation:

First convert mph to in/min.

35 mi/hr × (5280 ft/mi) × (12 in/ft) × (1 hr / 60 min) = 36960 in/min

The diameter of the wheel is 26 inches, so the circumference of the wheel is 26π inches. So the revolutions per minute is:

36960 in/min × (1 rev / 26π in) ≈ 452.5 rpm
