A fisherman travels downstream at full speed to his favorite fishing spot. The stream is running at a rate of 5 miles per hour, and he takes an hour to get to the fishing hole. He catches 5 fish and calls it a day. He takes twice as long at full speed to get back to the dock going against the current. How fast will his fishing boat go?

He catches 5 fish and calls it a day. He takes twice as long at full speed to get back to the dock going against the current. (x + 5)/(x - 5) = 2 x = 15 The full speed of the fishing boat is 15 miles per hour.
