Word problem

Question

Your car's fuel efficiency is 24.2 miles per gallon. You are going on a trip this weekend and will be driving a total of 272 1/4 miles. If gasoline costs $1.489 per gallon, about how much will the gas for this trip cost?

Answer 1

272.25/24.2=11.25 gallons

11.25*1.489=$ 16.75125

your answer will be $16.75.

Answer 2

MPG (miles per gallon) times gallons = miles

 

Therefore, gallons = miles / MPG

 

You're going 272 1/4 miles, which is 272.25, and your efficiency is 24.2.  So the number of gallons you use will be 11.25

 

Since gasoline costs $1.489 per gallon, multiply this by the number of gallons to get the cost, which is $16.75 (rounded to the nearest cent).
