A car is moving on a straight road. The velocity of the car varies with time as shown in the figure. Initially (at t=0), the car was at `x=0`, where, x is the position of the car at any time 't'.

Average speed from `t=0` to `t=70 s` will be :-

A

`16/7 m//s`

B

`24/7 m//s`

C

`20/7 m//s`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
B
Average speed
`=("Distance")/("time")=(20+40+60+80+40)/70=24/7 m//s`
