Check what is given in the question :

"A person travelling on a straight line moves with uniform vel  v1 for sometime and uniform velocity v2 for next equal time "

So v . t = v1 . t/2 + v2 . t/2

hence v =(v1 + v2)/2


Then its given that "v1 for dist x and uniform velocity v2 for dist x"

So you have to equate time

So 2x/ v = x/v1 + x/v2

So 2/v = 1/v1 + 1/v2
