Question
The distance covered by a boat while moving in
downstream in a fixed time is 3/4 more than in upstream. The speed of stream is what % of the still water speed of boat?Solution
As we can conclude that time is given constant, distance ∝ speed (v + u) / (v − u) = 175/100 (v) / (u) = 11/3 Required % = 3/11 x 100 = (27.27)%
