$$(a)$$
Displacement from O to P=360m
Time taken from O to P=18sec
Velocity of car =
Time
Displacement
=

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
