Question

Going against the current, a boat takes 6 hours to make a 120-mile trip. When the boat travels with the current on the return trip, it takes 5 hours.

If x = the rate of the boat in still water and y = the rate of the current, which of the following systems could be used to solve the problem?

Answer 1

5(x+y)=6(x-y)=120

x+y=24

x-y=20

x=22

y=2
