Upstream/Downstream problem. It takes 3 hours for a boat to travel 27 miles upstream. The same boat can travel 30 miles downstream in Upstream Downstream Algebra Word Problems Quota 2 hours. Find the speeds of the boat and the current. Solution. Let x be the speed of the boat (without a current). Let y be the speed of the current. Speed of the steamer in downstream = x +2 Speed of the steamer in upstream = x � 2 So time = Distance / speed Distance = speed x time D = (x +2) 4 D = (x � 2) 5 As the distance between the port is same. 4(x +2) = 5(x -2) 4x + 8 = 5x x = X = 18 Speed of the the steamer in still water = 18 m/h.
