A truck's odometer reads 25,711.3 miles at the beginning of a trip and 26,035.0 miles at the end. If the trip takes 14.8 gallons of gas, what is the gas mileage in miles per gallon? (Round to the nearest tenth)

Total distance covered = 26035 .0 - 25711.3 = 323.7 miles

Total gallons used = 14.8

miles per gallon = 323.7/ 14.8 = 21.87 = 21.9 miles per gallon
