Answer:
Her average speed is 48 miles per hour.
Step-by-step explanation:
We solve this question using a system of equations.
The speed equation is:

In which s is the speed, d is the distance, and t is the time.
Gabriella drives her car 320 miles and averages a certain speed.
So 
Then

If the average speed has been 6 miles less she could have traveled only 280 miles in the same length of time.
So, which s - 6, d = 280.

From the first equation:



Replacing:







Her average speed is 48 miles per hour.
First we have to find 18% of $55.82, which we can do by using the equation 55.82 x 0.18
55.82 x 0.18 = 10.05
so the tip = $10.05
now we just add it to the original bill
55.82 + 10.05 = 65.87
so the total cost = $65.87
