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 13 km/hr, the speed of the boy in still water is
Let the rate of swimming in still water be x km/hr Rate down-stream = (x + 13) km/hr Rate up-stream = (x – 13) km/hr According to the question, (x + 13) t = 3 (x – 13) × t x + 13 = 3x – 39 x = 26 km/hr
