A Man Swims Downstream 72 Km And Upstream 45 Km Taking 9 Hours Each Time. What Is The Speed Of The Current?

Answer»

MAN's DOWNSTREAM SPEED = 72/ 9 kmph => 8kmph

Man's up STREAM speed = 45/ 9 => 5 kmph

So speed of current = (8 - 5)/2 = 1.5 kmph.

Man's downstream speed = 72/ 9 kmph => 8kmph

Man's up stream speed = 45/ 9 => 5 kmph

So speed of current = (8 - 5)/2 = 1.5 kmph.
