Question
When travelling downstream, a boat takes 6 hours to
travel 240 km. If the speed of the stream is (3/8)th of downstream speed of the boat, then find the time taken by the boat to cover 300 km in still water.Solution
Downstream speed of the boat = 240/6 = 40 km/hr Speed of the stream = 40 x (3/8) = 15 km/hr So, speed of the boat in still water = 40 – 15 = 25 km/hr Required time taken = 300/25 = 12 hours
