Answer:
11 gallons of gas is needed to travel 231 miles.
Step-by-step explanation:
We can set up a proportion for this problem.

≈
So, you will need about 11 gallons of gas to travel 231 miles.
Start by dividing both sides by 3. Then take the square root of both sides. Then subtract 3 from both sides and divide by 2.
