A Man Rows upstream 36 km and downstream 48 kilometers
taking 6 hours each time the speed of the current is.Solution
Let the speed of boat in still water =B and speed of stream =S Speed in downstream (B+S) =48/6=8km/h Speed in upstream =B-S =36/6=6km/h B+S=8… (1) B-S=6 … (2) After solving Eq (1) and (2) B =7km/h S=1km/h Speed of stream =1km/h
