Asked by Chris Cook

A fisherman traveled in a boat from point N upstream. After having traveled 6 km, he stopped rowing and 4 hour 30 min after first leaving N, he was brought back to N by the current. Knowing that the speed of the boat in still water is 90 km/hour, find the speed of the river’s current.
Answered by Steve
since time = distance/speed,

6/(90-x) + 6/x = 4.5
x ≈ 1.35 km/hr
