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
:
%2860+%2A+5280+%2A+12%29%2F%28pi+%2A+22+%2A+60%29 = 917 rpm
