Question
A boat travels downstream at a speed of 25 km/h and the
stream's current adds an additional 3 km/h to its speed. How long will it take for the boat to travel 50 km downstream and then return 57 km upstream?Solution
Upstream speed of the boat = (25 - 6) = 19 km/h [Upstream speed = Downstream speed - 2 X speed of the stream] Total time taken by the boat to cover the required distance = (50/25) + (57/19) = 2 + 3 = 5 hours
