Answer:
11 gallons of gas is needed to travel 231 miles.
Step-by-step explanation:
We can set up a proportion for this problem.
For every 62 miles, you use 3 gallons of gas.
[tex]\frac{62}{3}*\frac{231}{?}[/tex]
Now, let's cross multiply.
[tex]\frac{693}{62}[/tex] ≈ [tex]11[/tex]
So, you will need about 11 gallons of gas to travel 231 miles.
