Question
A boat travels 600 metres against the stream in 20
seconds and returns the same distance with the stream in 15 seconds. Determine the speed of the boat in still water.Solution
ATQ,
Speed of boat in upstream = (600 / 20) = 30 m/s
Speed of boat in downstream = (600 / 15) = 40 m/s
Speed of the boat in still water = [(30 + 40) / 2] = 35 m/s
