Let total distance be s. Velocity to travel distance s/2

There is a formula 2/V_avg=1/v₁+1/v₂

Actually the question is indirectly asking the proof of this.

To calculate assume that the total distance be 2s.

during the first half ,time taken=s/V₁

during the second half ,time taken=s/V₂

V_avg=total distance /total time

V_avg=2s/(s/V₁+ s/V₂)

=>2/V_avg=1/v₁+1/v₂

SO if you are really helped by this solution then please approve this solution to encourage me.
