Mathematical Formulas & Calculation Methods

Road Trip Fuel Cost Formula

Divide trip distance by fuel efficiency (MPG) and multiply by gas price per gallon.

Total Fuel Cost = (Distance ÷ MPG) × Price per Gallon Per Person = Total Cost ÷ Passengers

Worked Step-by-Step Examples

Example 1: 300-Mile Trip at 25 MPG and $3.50/Gallon (4 Passengers)

"Calculate total gas cost and cost per person for a 300-mile trip in a car getting 25 MPG with gas priced at $3.50/gallon."

Steps:

Gallons needed: 300 ÷ 25 = 12 gallons
Total fuel cost: 12 × $3.50 = $42.00
Cost per person: $42.00 ÷ 4 = $10.50 per person

Result: Total Gas Cost: $42.00 ($10.50 per passenger).
