Question

arshad can cover a circular path of radius 21m in 44 seconds he will cover a distance of 3km​

Answer 1

Answer:

Circumference of circular path = distance covered by Arshad = 2πr

here r =21m

so Circumference = 2*22*21/7 = 132m

time taken to cover  132m is 44 seconds

so speed = distance/time

i,e S = 132/44 m/s = 3m/s

Now Arshad wants to cover a distance of 3Km

so here Distance = 3Km

time ?

Speed = 3m/s

so time = distance/speed = 3000/3 = 1000 seconds
