Question

Hari singh can cover a circular path of radius 21 m in 44 seconds. He will cover a distance of 3km in how much time??
plz ans with explanation​

Answer 1

Answer:

oh sure

circumference of circle= 2πr =2×22/7×21 =132m

here given that Hari Singh can cover a circular path in 44 seconds so a speed of Hari Singh

= 132/44 =3 m/s

this speed is in meter per second unit we have to convert it into kilometer per second unit.

3m= 3/1000 km

therefore

speed=0.003 km/s

therefore time taken to cover 3 km distance = 3/0.003 =1000 second or 16.666...... sec
