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
