Final answer:
The unit rate of 65 miles in 2.7 gallons is 24.07 miles/gallon.
Step-by-step explanation:
A unit rate is a comparison of two different quantities when one of them is expressed as a single unit. It is a rate in which the denominator is one unit. In other words, a unit rate is the amount of one quantity for a given unit of another quantity.
To calculate the unit rate, divide the distance (in this case, 65 miles) by the amount of gasoline used (2.7 gallons). So, the unit rate is 65 miles / 2.7 gallons = 24.07 miles/gallon. Therefore, the correct option is A. 24.07 miles/gallon.
