Formula
Time = Distance / Speed | Fuel = Distance / MPG | Cost = Fuel x Price
Driving time is distance divided by average speed. Fuel consumption is distance divided by fuel efficiency (mpg). Total trip cost is gallons used multiplied by fuel price per gallon.
Worked Examples
Example 1: Weekend Road Trip Calculation
Problem:Plan a 450-mile road trip at 60 mph average speed, 30 mpg fuel efficiency, $3.60/gallon gas, with 3 rest stops of 15 minutes each.
Solution:Driving time: 450 / 60 = 7.5 hours (7h 30m)\nRest stop time: 3 x 15 = 45 minutes\nTotal trip time: 7h 30m + 45m = 8h 15m\nFuel needed: 450 / 30 = 15.0 gallons\nFuel cost: 15.0 x $3.60 = $54.00\nCost per mile: $54.00 / 450 = $0.12/mile
Result:Total time: 8h 15m | Fuel: 15.0 gal ($54.00) | $0.12/mile
Example 2: Cross-Country Drive Estimation
Problem:Calculate a 1,200-mile cross-country drive at 55 mph average, 25 mpg, $3.80/gallon, with 6 stops of 20 minutes each.
Solution:Driving time: 1,200 / 55 = 21.8 hours (21h 49m)\nRest stop time: 6 x 20 = 120 minutes (2 hours)\nTotal trip time: 21h 49m + 2h = 23h 49m\nFuel needed: 1,200 / 25 = 48.0 gallons\nFuel cost: 48.0 x $3.80 = $182.40\nCost per mile: $182.40 / 1,200 = $0.15/mile
Result:Total time: 23h 49m | Fuel: 48.0 gal ($182.40) | $0.15/mile
Frequently Asked Questions
How is driving time calculated from distance and speed?
Driving time is calculated using the fundamental physics formula: Time = Distance divided by Speed. For example, a 300-mile trip at an average speed of 60 mph takes 300 / 60 = 5 hours of pure driving time. However, real-world driving time is always longer due to rest stops, fuel stops, traffic delays, and speed variations through towns and construction zones. Most trip planners recommend adding 10-15 percent to calculated driving time for these variables. Interstate highway driving typically averages 55-65 mph accounting for speed limit variations, while mixed highway and city driving averages 40-50 mph depending on traffic density.
