Question

Of Mukesh walks around a circular track of radius 14m.
If he takes 20 rounds of the track. Find the total
distance covered by Mukesh.​

Answer 1

Step-by-step explanation:

Radius of circular track = 14m

Circumference of the circular track= 2πr= 2×22/7×14=88

Total distance covered 20 round = 88×20

= 1760 m

Speed of Mukesh on the circular track 4km/h

4×1000/60= 2×100/3= 200/3 m

Time taken Mukesh = 1760/200/3

= 1700×3/200

= 176×3/20

= 26 minutes 24 second
