Question

You plan to take a 1524​-mile trip in your​ car, which averages 24 miles per gallon. How many gallons of gasoline should you expect to​ use? Would a car that has only half the gas mileage require twice as much gasoline for the same​ trip? Explain

Answer 1

(a) (1524 mi)/(24 mi/gal) = 63.5 gal

(b) Yes. If the number in the denominator of the above equation is cut in half, the quotient (gallons required) is multiplied by 2.
