Question

A cyclist goes around a circular track once every two minutes. If the radius of the circular track is 105 mts calculate his speed (use 22/7)

Answer 1

Time taken = 2 minutes = 120 sec

Radius = 105 m

 Circumference of circular track = 2 x 22/7 x 105 = 660m

Speed = distance / time = 660/ 120 =5.5m/s
