A swimmer swims from point P against the current for 6
minutes and then swims back along the current for the next 6 minutes and reaches point Q. If the distance between P and Q is 120 m then the speed of the current (in km/ h) is:Solution
Let the speed of boat in still water =B and speed of stream =S then Given-Time in Upstream and Downstream =6 min And Distance between P And Q =120m Speed of boat in Downstream =B+S Speed of boat in Upstream=B-S ATQ- 6(B+S)-6(B-S) =120 6B+6S-6B+6S=120 12S =120 S=10×60/100 S= .6km/h
