Question
In a fixed time, a boy swims thrice the distance along
the current that he swims against the current. If the speed of the current is 9 km/hr, the speed of the boy in still water isSolution
Let the rate of swimming in still water be x km/hr Rate down-stream = (x + 9) km/hr Rate up-stream = (x – 9) km/hr According to the question, (x + 9) t = 3 (x – 9) × t x + 9 = 3x – 27 x = 18 km/hr
