Nitin walks around a circular track of radius 14m with a speed of4 km/hr. if he takes 20 round of the track for how long does he walk?

Answer»

Circumference of circle = 2*(22/7)*14= 88m. Total distance hr walks = 88*20= 1760m. Time = Distance / Speed = 1760/(4*(18/5))= 1760/ (72/5)= (1760*5)/72= 122.222 seconds
