Answer:
Average speed is 3m/s and Average velocity is zero.
Explanation:
Average speed = Total distance / Total time
= 240m/80sec
= 3m/s
Displacement is the straight line distance between initial and final position.
Rohit's initial and final position is same.
Therefore, displacement is zero.
Average Velocity = Total displacement / Total time
= 0m/80sec = 0
