Question
When travelling downstream, a boat takes 5.25 hours to
travel 252 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 = 252/5.25 = 48 km/hr Speed of the stream = 48 x (3/8) = 18 km/hr So, speed of the boat in still water = 48 â 18 = 30 km/hr Required time taken = 300/30 = 10 hours
