A car is traveling along Route 66 at a rate of 75 miles per hour, and the diameter of its wheels are 2.4 feet. Find the number of revolutions per minute the wheels are turning. Round answer to one decimal place.

Thanks in advance!

wheel circumference is 2.4xpi=2.4x3.1415926=7.53982224 ft

75mph=395989.17ft/h

395989.17/7.53982224=52519.69rot/h = 875.33 rot/min
