Question

Lamonte's car used 5 gallons to travel 125 miles. How many gallons of gas would he need to travel 400 miles?

Answer 1

16 gallons

Explanation:

We can use a ratio to solve this problem.

5 gallons x gallons

---------------- = -------------

125 miles 400 miles

Using cross products

5 * 400 = 125 x

Divide each side by 125

5 * 400/125 = 125x/125

16 =x
