Given function: f(x) = 120 - 25x

Replace f(x) with 0. Then solve for x.

f(x) = 120 - 25x
0 = 120 - 25x
0+25x = 120 - 25x+25x
25x = 120
25x/25 = 120/25
x = 4.8

The 120 refers to how far the ship is from the destination at the beginning of the trip. Then 4.8 hours later, the distance from the destination is 0 miles.

The ship traveled 120 miles in 4.8 hours.
