The car always uses the same amount of gas each mile.

Let us find out how much gas the car uses per mile:

After 110 miles, it used 2.75 gallons.

Therefore, the amount of gas used per mile is:

100 / 2.75 = 40 gallons per mile

Btw Dividing 220 by 5.5 and 300 by 7.5 yields the same result.
Therefore, after 430 miles, the number of gallons used will be:

430 / 40 = 10.75 gallons
