Question
On Friday, if ratio of the speed of boat to the speed of
stream is 2:1, then what is the difference between the time taken by the boat while going upstream and downstream? Study the following table carefully and answer the given questions: Distance Upstream = Distance Downstream Total time taken = Downstream time + Upstream timeSolution
Let the speed of the boat and speed of the stream be 2x and x km/hr respectively. According to question, => [360/(2x+x)] + [360/(2x-x)] = 60 => (360/3x) + (360/x) = 60 => x = 8 The speed of stream is 8 km/hr and the speed of boat is 16 km/hr. Required difference = (360/8) - (360/24) = 30 hours
