## Trip Gas Price Formula

The following formula is used to calculate the Trip Gas Price.

GP = D / FE * C

- Where GP is the Trip Gas Price ($)
- D is the total trip distance (miles)
- FE is the fuel efficiency of the car (MPG)
- C is the average cost of gas ($/gallon)

## How to Calculate Trip Gas Price?

The following example problems outline how to calculate Trip Gas Price.

**Example Problem #1**

- First, determine the total trip distance (miles).
- The total trip distance (miles) is given as 250.

- Next, determine the fuel efficiency of the car (MPG).
- The fuel efficiency of the car (MPG) is calculated as: 30.

- Next, determine the average cost of gas ($/gallon).
- The average cost of gas ($/gallon) is found to be: 3.00.

- Finally, calculate the Trip Gas Price using the formula above:

GP = D / FE * C

Inserting the values from above yields:

GP = 250 / 30 * 3 = 25.00 ($)

**Example Problem #2**

The variables needed for this problem are provided below:

total trip distance (miles) = 700

fuel efficiency of the car (MPG) = 25

average cost of gas ($/gallon) = 4.50

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
