A boat traveled 170 miles downstream and back. The trip downstream took 10 hours. The trip back took 34 hours. Find the speed of the boat in still water and the speed of the current.

The boat's speed is the average of the 2 groundspeeds.
The current is the difference between the boat's speed and either groundspeed.
