Asked by Kylie C.

The diameter of each tire on Niki's bike is 66 centimeters (cm). It takes her 16 minutes to ride 10 kilometers (km).

How fast did Niki ride, in kilometers per hour?

thx in advance =D

Did you realize that the size of Niki's bike is irrelevant?

Since Rate = Distance/ time
Rate = 10/(16/60) km/h = 37.5 km/h
