A car is moving at a rate of 60 miles per hour. the diameter of the wheels are 2.6 ft.

how do you find the revolutions per minute that the wheels are rotating?
Answered by Ms. Sue
The car travels one mile in one minute.

C = pi * d
C = 3.14 * 2.6
C = 8.164 feet

5,280 / 8.164 = 646.74 revolutions per minute
