Question

You want to buy a new car. The car averages 45 miles per gallon. It has a range of 675 miles on one tank of gas. How many gallons of gas will the car hold when the tank is full?

Answer 1

The gas tank capacity of the car is found by dividing the range by the fuel economy. With a range of 675 miles and a fuel economy of 45 mpg, the car's gas tank can hold 15 gallons of gasoline when full.

Step-by-step explanation:

The student's question is about finding the gas tank capacity in gallons of a new car that has an average fuel economy of 45 miles per gallon (mpg) and can travel a range of 675 miles on a full tank. To solve this problem, we use the formula for calculating fuel usage:

Range (in miles) = Fuel Economy (in mpg) × Gas Tank Capacity (in gallons)

To find the gas tank capacity, we rearrange the formula:

Gas Tank Capacity (in gallons) = Range (in miles) / Fuel Economy (in mpg)

Thus:

Gas Tank Capacity = 675 miles / 45 mpg = 15 gallons

This means the car's gas tank can hold 15 gallons of gasoline when full. It's important to note that this is a straightforward division problem that can be easily solved without the need for a calculator or advanced mathematics.

Answer 2

To find out how many gallons of gas the car will hold, divide the total number of miles traveled on one tank of gas by the average miles per gallon.
675/45 = g
g = 15
The tank can hold 15 gallons of gas.
