A thief is running away on a straight road in a moving with a speed of `9 ms^(-1)`. A policeman chases him on a motor cycle moving at a speed of `10 ms^(-1)`. If the instantaneous separation of the jeep from the motor cycle is `100 m`, how long will it take for the policeman to catch the thief ?.

A

1s

B

19s

C

90s

D

100s

Text Solution

Verified by Experts

The correct Answer is:
D
The relative velocity of policeman w.r.t thirf`=10-9=1(m)/(s)`.
`because` Time taken by police to catch the thief`(100)/(1)=100`sec
