Question

Trina's car uses 12 gallons of gas to travel 144 miles. If she has 6 gallons of gas in the tank, how much more gas will she need to drive 240 miles?

Answer 1

Answer: 14gallons

Explanation:

12gallons/144miles = 1gallon/12miles

Therefore 6gallons = 12*6 = 72miles.

In order to cover 240miles, she will need 240/12 = 20gallons.

20-6 = 14gallons

She will need 14gallons of gas more.
