She traveled 23.5 miles on each gallon of gas.

Step-by-step explanation:

According to the information given in the exercise, you know the following:

1. The las time the odometer read:

$x_1=21,865.3\ miles$

2. And this time the odometer read:

$x_2=22,123.8\ miles$

So, knowing this, you can find the difference through this subtraction:

$x_2-x_1=22,123.8\ miles-21,865.3\ miles=258.5\ miles$

Therefore, based on that you can conclude that Gloria traveled 258.5 miles this time.

Since Gloria put in 11 gallons of gas, you can calculate the amount of miles she traveled on each gallon of gas by dividing 258.5 miles by 11 gallons.

Therefore, the result is:

$\frac{258.5\ miles}{11\ gallons}= 23.5\ \frac{miles}{gallon}$
