The distance around the tire of a motorized scooter is 21.98 inches. The tires make one revolution every 1/10 second. Rounding to the nearest tenth, what is the speed of the scooter in miles per hour?

Respuesta :

Find the speed of the Scooter in miles/hr.
Speed = distance/time
Distance = 21.98 inches = 0.00034548611miles
Time = 10 seconds = 0.00277778 hrs.

Speed = 21.98/10
Speed = 2.198 inches/seconds
or
Speed = .12miles/hr.
