Answer:
He walks for 26 min 24 sec.
Step-by-step explanation:
Radius of the circular track = 14 m
Circumference of circular track = 2 x 22/7 x 14 = 88m
Total distance covered by mukesh= 88m x 20= 1760m
Speed of mukesh= 4 km/hr
So, total time taken = 60/4 x 1760/1000 = 26.4 min = 26min 24sec
Hope it will help you!

Answer:
33 mins
Step-by-step explanation:
perimeter of circular track=2πr=2×22/7×14=88
=88m^2
rounds he took=25
distance=25×88=2200m^2
T=D/S
T=2200/1000×60/4
T=33mins
