Respuesta :

Answer:

She still has 304 miles left after traveling for 12 hours

Step-by-step explanation:

Here, we want to calculate the number of miles Johanna has left on her trip.

The equation linking the distance , speed and time is;

F(t) = 1084 -65t

Now, for t = 12, we simply make a direct substitution;

F(12) = 1084 - 65(12)

F(12) = 1084 - 780

F(12) = 304 miles
