Answer 1

Answer: Average speed = 1.5m/s. And Average velocity = 0 m/s

Explanation: distance = 180 m

Time taken = 2minutes = 2×60= 120 sec

Now , find average speed

Average speed or V.av = total distance / total time

= 180+180 / 120+120

= 360 / 240

=. 1.5m/s

Displacement = 0m/s

Time = 240 sec

Average velocity = total displacement / total time

= 0 / 240

= 0m/s

Because he returned to home .
