Question

A car with an odometer reading of 17,814.2 contains 11.2 gallons of gas. At an odometer reading of 18,096.4, the tank is empty and the car is filled with 12.4 gallons of gas. How many miles does the car travel on 1 gallon of gasoline? (Round your answer to one decimal place.)

Answer 1

18,096.4 - 17,814.2 = 282.2 miles

 

(282.2 miles)/(11.2 gal) ≈ 25.2 miles/gal

 

The car travels about 25.2 miles on one gallon of gasoline.  

Answer 2

The car has traveled 18096,4 - 17814,2 =  282.2 miles on 11.2 gallons of gas.

Then the miles per gallon of the car is 282.2 mi/11.2 gallons ≈ 25.2 miles/gallon
