Question

Writing expression for the Problem

Frank was going on Trip. He filled his car with 14 gallons of gas. He then drove to his destination and used 14 gallons of gas

Answer 1

14 gallons

trip distance = miles = m/gal x gallons = mpg x gallons = 14x mpg

d = 14mpg miles

similar to the d=rt formula where r= rate of speed and t = time

but now it's

d =14mpg= rate of miles per gallon times gallons

to find the distance of the trip multiply 14 by the miles per gallon of the vehicle

14x28 (using 28 mpg as a rough estimate) = 787 miles

or

to find the mpg of the vehicle: mpg = d/14

= 14x28/14 = 28 mpg
