A boat traveled 180 miles each way downstream and back. The trip downstream took 9 hours. The trip back took 18 hours. Find the speed of the boat in still water and the speed of the current.

since distance = speed * time,
If the boat's speed is b and the stream's speed is s, then
9(b+s) = 180
18(b-s) = 180
Now just solve for b and s
If the boat's speed is b and the stream's speed is s, then
9(b+s) = 180
18(b-s) = 180
Now just solve for b and s
