Returning, he finds that the trip downstream, still at top speed takes only 4.5 hr. Find the rate of Bills boat and the speed of the current. Let x = the rate of the boat in still water and y = the rate of the current.

Find the speed up and downstream.
The boat's speed x is the average of those.
y = difference between boat speed and ground speed.
