Answer:

There can be a number of correct answers. One of them is the ship has traveled 25 miles in 1 hour.

Step-by-step explanation:

The distance from destination f after x hours for the ship is given by f(x)=120-25x

At the beginning, x=0, f(x)=f(0)=120

After 1 hour, f(x)=f(1)=120-25=95

So in 1 hour, the ship has traveled 120-95=25 miles.

Answer:

Ship travels 100 miles in 4 hrs

Step-by-step explanation:

distance = 120 - 25x

in 4 hrs, distance = 120 - 25*4 = 20

distance traveled in 4 hrs = 120 - 20 = 100 miles
