Question

Choose the best answer to the following question. Explain your reasoning with one or more complete sentences.

You are given two pieces of​ information, (1) the price of gasoline in dollars per gallon and​ (2) the gas mileage of a car in miles per gallon. You are asked to find the cost of driving this car in dollars per mile. What should you​ do?

Answer 1

To calculate the cost of driving in dollars per mile, divide the price of gasoline by the gas mileage of the car. Using this method, a vehicle with a $3.00 per gallon gas cost and 30 mpg efficiency would cost $0.10 per mile to operate.

Step-by-step explanation:

To find the cost of driving a car in dollars per mile, you need to divide the price of gasoline in dollars per gallon by the gas mileage of the car in miles per gallon. This calculation will give you the cost to drive one mile in that particular car.

For example, if gasoline costs $3.00 per gallon and a car gets 30 miles per gallon, the cost per mile would be calculated as follows:

Cost per mile = Price per gallon / Miles per gallon
Cost per mile = $3.00 / 30 mpg
Cost per mile = $0.10

Therefore, it costs $0.10 to drive this car for one mile.
