The wheels on Jason's dirt bike measure 19 inches in diameter. How many revolutions will the wheels make when Jason rides for 500 feet?

Diameter of wheel = D = 19 in = 19/12 ft

radius of wheel = r = 19/24 ft

So when the wheel covers one revolution it will cover distance equal to its circumference S = 2πr = 2*3.14*19/24 = 4.97 ft

total no of revolutions = 500/4.97 = 100.6
