A Car goes 120 metres in 5 seconds eastbound on a straight route, then 60 metres in 1 second westbound. Calculate the average speed and velocity.

Total Distance = 120 m + 60 m = 180 m
Total Displacement = 120 m – 60 m = 60 m, towards east.
Time Taken = 5s + 1s= 6 s
Average speed = Distance / time taken
= 180 m / 6 s
= 30 m/s
Average velocity = Displacement / time taken
= 60 m / 6 s
= 10 m/s
