Question

A man runs 120 m to win a race and covers a distance of 240 m in going a coming back to the point of start. Find average speed , Average velocity, Total displacement?

Answer 1

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.

mark me as brainliest

Answer 2

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
