**How A cars fuel efficiency is 25 mpg in the city and 35 mpg on the highway. If a driver travels 300 miles (15 urban, 285 highway), how many gallons are used?** As fuel prices remain a top concern and efficiency rankings shape consumer choices, many U.S. drivers are asking: *What’s my real-world fuel use for a typical long drive?* A vehicles with a combined fuel efficiency of 25 miles per gallon (mpg) in the city and 35 mpg on the highway face a practical challenge: calculating their gas needs without complex formulas. Understanding how to translate these numbers into gallons helps guide smarter travel planning and budgeting—whether planning weekend road trips or managing daily commutes. The math is straightforward when broken into real-world context. For a 300-mile trip—15 miles in city driving and 285 miles on highways—the fuel used can be found by applying each efficiency rating separately. City driving at 25 mpg consumes 300 ÷ 25 = **12 gallons**.
Highway segments at 35 mpg require 285 ÷ 35 ≈ **8.14 gallons**.
