Example: Trip Cost Calculation
Let’s use a real-life example to understand the calculation.
Trip Details
- Distance: 300 miles (one way)
- Vehicle Mileage: 25 MPG
- Gas Price: $4.00 per gallon
Step 1: Calculate Fuel Needed
Fuel Needed = Distance ÷ MPG
= 300 ÷ 25
= 12 gallons
Step 2: Calculate Trip Cost
Trip Cost = Fuel Needed × Gas Price
= 12 × $4
= $48
Final Trip Estimate
- Fuel Required: 12 gallons
- Total Cost: $48
- Cost Per Mile: $0.16
If the trip is round-trip, total cost becomes $96.
