You can put this solution on YOUR website! A motorboat travels 441mi in 7 hours going upstream and 522mi in 6 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
-------------------
441/7 = 63 mph
522/6 = 87 mph
The boat's speed is the average (63 + 87)/2 = 75 mph
The current is the difference 87 - 72 = 12 mph
