Question
A man rows to a place 48 km distant and comes back in 14
hours. He finds that he can row 4 km with the stream at the same time as 3 km against the stream. The speed of the stream is.Solution
Let the speed of boat in still water =B and speed of stream =S then Speed of boat in downstream=B+S and distance =4km So now -time =4/B+S Speed of boat upstream =B-S and Distance =3km So, time = 3/B-S ATQ- 
S= 1 km/h
