A motorboat takes 3 hours to travel 108 going upstream. The return trip takes 2 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
1 answer:
Let s and c be the rate of the boat in still water and the rate of the current, respectively. Then: 108/s-c=3 108/s+c=2 3s-3c=108 2s+2c=108 Solve for s and c ☺☺☺☺
