Question
A boat covers a certain distance against the stream in 9
hours 36 min and it covers the same distance along the stream in 6 hours. What is the ratio of the speed of the boat in still water to that of the stream?Solution
Let the speed of boat in still water =B and speed of stream =S then Speed of boat in Downstream =B+S, and Time = 6h Speed of boat in Upstream=B-S, Time = 9 h 36min=96/10=48/5h ATQ- 48/5(B-S) =6(B+S) 
B-S=10 … (1) B+S=16 … (2) B=13, S=3 Now ratio of boat speed and stream speed = 13:3
