Total displacement = (v1 × t/2) + (v2 × t/2)
= (v1 + v2)t/2
Mean velocity = Total displacement / Total time
= [(v1 + v2)t/2] / t
= (v1 + v2) / 2
Mean velocity of man is (v1 + v2) / 2
= (v1 + v2)t/2
Mean velocity = Total displacement / Total time
= [(v1 + v2)t/2] / t
= (v1 + v2) / 2
Mean velocity of man is (v1 + v2) / 2

Its wrong
send a proper solution
What is correct answer?
The correct answer is 2v1v2/v1+v2
Its a CET problem (Basic level 1)
My answer is correct. I think there is a mistake in your key.
wait ill try
