D 22.5 miles per gallon
thx
To find the unit rate, which is the amount of one quantity per unit of another quantity, we need to divide the two quantities given in the problem.
In this case, we need to divide the distance, which is 270 miles, by the amount of gas, which is 12 gallons.
Therefore, the unit rate is 270 miles / 12 gallons.
Simplifying this fraction, we get:
270 miles / 12 gallons = 22.5 miles per gallon
So the correct answer is (D) 22.5 miles per gallon.
