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 expressions represents the rate of the boat going with the current?

Answer 1

x+y

Explanation:

Answer 2

(x+y)

24 miles per hour.

Explanation:

If the boat has a speed of x in still water and the current has a speed of y, then (x+y) will represent the speed of the boat while going with the current.

It is given that the boat takes 5 hours to travels 120 miles trip with the current on the return trip.

Therefore, the speed of the boat while going with the current will be (
`(120)/(5)`) =24 miles per hour.

And, 24 miles per hour will be equal to (x+y). (Answer)
