Question
A boat goes 40km upstream in 8 hours and 36km downstream
in 6 hours. The speed of the boat in still water.Solution
Let the speed of boat in still water =B and speed of stream =S Speed of boat in downstream B+S=36/6=6km/h Speed of boat in upstream =B-S=40/8=5km/h Now Speed of boat in still water B= (6+5)/2 =11/2=5.5km/h
