murphy can row at 5kmph in still water. If the velocity of the current is 1kmph and it takes him 1 hour to row to the place and back, how far is the place?

A question from physics homework that is really confusing me

Jagadeesh E.

If the distance is X and Velocities in Up stream and down stream will be 5 -1 =4KMPH and 5+1 = 6KMPH respectively.
So Distance/velocity = time.
X/6 + X / 4 = 1 hour
10X = 24
x = 2.4
