A Boatman Can Row 96 Km Downstream In 8 Hr. If The Speed Of The Current Is 4 Km/hr, Then Find In What Time Will Be Able To Cover 8 Km Upstream?

Answer»

Speed DOWNSTREAM =96/8 = 12 kmph

Speed of current = 4 KM/hr

Speed of the boatman in still water = 12-4 = 8 kmph

Speed upstream = 8-4 = 4 kmph

Time TAKEN to cover 8 km upstream =8/4 = 2 hours.

Speed downstream =96/8 = 12 kmph

Speed of current = 4 km/hr

Speed of the boatman in still water = 12-4 = 8 kmph

Speed upstream = 8-4 = 4 kmph

Time taken to cover 8 km upstream =8/4 = 2 hours.
