Question 238706
A tire for a compact car is 22 inches in diameter. If the car is traveling at a speed of 60 mi/hr, find to the nearest integer the number of revolutions the tire makes per minute.
:
60 mph * ft in 1 mi * 12 inches, divided by circumference and 60 min
:
{{{(60 * 5280 * 12)/(pi * 22 * 60)}}} = 917 rpm
