Lucy bought a new car that has a 18 gallon gas tank. If she can drive 270 miles on a full tank of gas, what is the unit rate of miles per gallon he gets? * 1 point 18 miles per gallon 252 miles per gallon 15 miles per gallon 288 miles per gallon

To calculate the unit rate of miles per gallon, divide the number of miles by the number of gallons.

The unit rate is 270 miles per 18 gallons.

Simplifying the fraction, we get:

270/18 = 15/1

Therefore, Lucy gets 15 miles per gallon.

So, the correct answer is:

15 miles per gallon.
