Question

rajesh takes 15 second to walk 100 metre. how much time will he take to cover 5 kilometre​

Answer 1

Answer:

time taken by Rajesh to cover 1 km = 150 sec

time taken by Rajesh to cover 5 km= 150×5= 750 sec

Answer 2

Answer:

750 sec

Explanation:

speed =dist/time

speed=100/15

speed=20/3 m/s

to cover 5 km = 5000 m

dist=speed/time

time=dist/speed

time=5000/(20/3)

time=(5000 x 3)/20

time=250 x 3

time=750 sec
