Example: How Much Will a Trip Cost?
Let’s say you’re traveling 175 miles in a car that averages 28 MPG, and the current gas price is $3.59 per gallon.
Fuel Calculation:
- Gallons required: 175 ÷ 28 = 6.25 gallons
- Total cost: 6.25 × $3.59 = $22.44
- Cost per mile: $22.44 ÷ 175 = $0.13 per mile
✅ Results:
| Output | Value |
|---|---|
| Gallons Needed | 6.25 gal |
| Total Trip Cost | $22.44 |
| Cost Per Mile | $0.13 |
