A swimmer swims from a point A against a current for 5
minutes and then swims current for next 5 minutes and comes to the point B. If AB is 100meters, the speed of the current is (km/h).Solution
. Let the speed of boat in still water =B and speed of stream =S Distance covered by downstream speed in 5 minutes =(B+S) ×5/60 Distance covered by downstream speed in 5 minutes=(B-S) ×5/60 ATQ- 
S=6/10 =0.6km/h Speed of current =S= 0.6km/h
