A van travels 220 miles on 10 gallons of gas. Find how many gallons the van needs to travel 550 miles.

31 gallons of gas

121 gallons of gas

25 gallons of gas

115 gallons of gas

The van will need 25 gallons of gas for it to travel 550 miles. This is calculated by dividing 10 gallons to 220 miles to get the miles per gallons, which in this case is 22 miles per gallon. Then we have to divide 550 miles by 22 miles per gallon to get the total gas consumption, which is 25 gallons.
