A bus is moving with a velocity `10 ms^-1` on a straight road. A scooterist wishes to overtake the bus in `100 s`. If the bus is at a distance of `1 km` from the scooterist, with what velocity should the scooterist chase the bus ?

A

`50 ms^-1`

B

`40 ms^-1`

C

`30 ms^-1`

D

`20 ms^-1`

Text Solution

Verified by Experts

The correct Answer is:
D
Let the velocity of the scooter be `v ms^-1`. Then
`(v - 10)100 = 1000` or `v = 20 ms^-1`.
