Case 1: Josh started running away from B towards A.
They will meet in between A and B
As per the question, Hosh turns back after meeting Josh and reaches point B, it is not possible in this case.
Case 2: Josh started running away from B opposite to A.
Let the point at which they meet is C and BC = x metres.
So, by the time Hosh had travelled a distance of 80 + x, Josh had travelled a distance of x.
As time is constant
From (1) and (2) we get
We get x = 20
So, total distance travelled by Hosh = 80 + 2x = 120m
