If it take 18 gallons of gas to 400 miles how many gallons of gas would it take to go 300 miles

Answer 1

To find out how many gallons of gas would be needed to go 300 miles, we can set up a proportion using the given information:

18 gallons of gas / 400 miles = x gallons of gas /300 miles

Cross-multiplying, we get:

(18 gallons of gas) * (300 miles) = (400 miles) * (x gallons of gas)

5400 gallons*miles = 400x gallons*miles

Dividing both sides by 400:

5400/400 = x

Simplifying:

13.5 = x

Therefore, it would take 13.5 gallons of gas to travel 300 miles.
