A tugboat goes 120 miles upstream in 15 hours. The return trip down stream takes 10 hours. Find the speed of the tugboat without a current and the speed of the current.
------------
The boat's speed is the average of the upstream and d/stream speeds.
The current is the difference between the boat's speed and the up or d/stream speed.
