Lanier review 30

Question

you drive 252 miles and have 9 gallons of gas remaining in your tank. Then you continue driving, and calculate that after driving 318 miles you have 6 gallons left.

What is your rate?

   miles per gallon

Answer 1

It took 3 gallons of gas to drive 66 miles ( 318 - 252) since the gas tank had 6 gallons after traversing that distance. If you divide 66 by 3 you get 22 miles, which means the rate is 22 miles per gallon. Feel free to contact me if you would like to schedule a tutoring session !

Answer 2

The 1st information is extra except for the 9 gallons left. The second part you went 318 miles with 6 gallons left. Take the miles you went and divide by the gallons you used (3 gallons) in order to find miles per gallon.
