Step-by-step explanation:
Radius of the circular track = 14 m
Circumference of the circular track = 2πr = 2×22/7×14 = 44×2 = 88 m
Total distance cover in 20 rounds = 88×20 = 1760 m
speed of Mukesh on the circular track = 4Km/h
=
60
4×1000
=
3
2×100
=
3
200
m/min
Time taken by Mukesh =
3
200
1760
=
200
1760×3
=
20
176×3
= 26.4 min
26.4 min = 26 min and 24 sec.
