ANSWER

$$(a)$$

Displacement from O to P=360m

Time taken from O to P=18sec

Velocity of car =

Time

Displacement

=

18

360m

Avg. Velocity of car (O to P)=20ms

−1

Time taken from P to Q=6sec

Total time taken to move from O to P and back at Q,

T

=16+6=24

Displacement from P to Q=240m

Average speed of car from P to Q=

24sec

240m

=10ms
