When a crew rows with the current, it travels 18 miles in 2 hours. Against the current, the crew rows 5/9 of the distance in 2 hours. Let x=the crew rowing rate in still water and let y=the rate of the current. Find the rate of rowing in still water and the rate of the current.

Find the speed upstream and d/stream.
The crew's speed is the average of the 2.
The current is the difference.
