Question 885797: In his motorboat, Bill Ruhberg travels upstream at top speed to his favorite fishing spot, a distance of 36 mi, in 2 hr. Returning, he finds that the trip downstream, still at top speed, takes only 1.5 hr. Find the rate of Bill's boat and the rate of the current. Let x = the rate of the boat and y = the rate of the current.

You can put this solution on YOUR website!
Use d = r*t --> r = d/t to find the speed up and down stream.
The boat's speed is the average.
The current is the difference.
