Explanation:
total displcement=0
as he comes back to the same point
total velocity =0
as the displcement is zero
we cannot find speed in this case because time is not given.

Answer:
total displacement = 0
average velocity = 0
average speed = 2 metre per second
Explanation:
total displacement will be zero as he come back to the starting point
average velocity will be zero as displacement is negligible
Given
distance=240 m
time=120 s
speed = distance / time
speed = 240/120
speed = 2 m/s
