A car travels 240 miles using 8 gallons of fuel. If the cars fuel efficiency improves by 20% on a subsequent trip, how many miles can it travel on 10 gallons of fuel?

**How improved fuel efficiency unlocks longer travel: What a 240-mile, 8-gallon baseline reveals** Have you ever wondered how a car that fetches 240 miles on 8 gallons of fuel could drive even farther with a small gain in efficiency? In today’s climate-conscious and cost-sensitive driving environment, optimizing fuel use isn’t just about saving money—it’s about smarter travel planning and reducing environmental impact. This is especially relevant as U.S. drivers increasingly track mileage and efficiency amid rising fuel costs and growing interest in greener transportation. The real-world math here is straightforward: a vehicle getting 240 miles per 8 gallons achieves 30 miles per gallon (mpg). That baseline version of fuel performance opens new possibilities when efficiency improves. With a 20% gain, fuel economy rises to 36 mpg. On 10 gallons, that means traveling 360 miles—more range for the same fuel input. This simple shift transforms daily commutes, road trips, and vehicle planning with clearer, more confident expectations. ### Why this efficiency puzzle is gaining traction
