A car is moving along a straight (OP). It moves from `O to P` in `18 seconds` amd retuns from `P to Q` in 6 seconds`, where `OP=360 m` and `OQ=240 m What are the car the average velcoty and average speed of the car in going (a) from `Oto P` and back to `Q` ?

A

`10ms^(-1), 20ms^(-1)`

B

`20ms^(-1), 10ms^(-1)`

C

`10ms^(-1),10ms^(-1)`

D

`20ms^(-1), 20 ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`v_("avg") = ("total displacement")/("total time") = (s_(1) + s_(2))/(t_(1) + t_(2))`
