3. A van travels 180 miles on 12 gallons of gas. At that rate, how much gas will it need to travel 330 miles?

To find out how much gas the van will need to travel 330 miles, we first determine the van's fuel efficiency. The van travels 180 miles using 12 gallons, giving it a fuel efficiency of 15 miles per gallon (180 miles ÷ 12 gallons). Now, to find out how much gas is needed for 330 miles, divide the distance by the fuel efficiency: 330 miles ÷ 15 miles per gallon = 22 gallons. So, the van will need 22 gallons of gas to complete the trip! It's interesting to consider how fuel efficiency can fluctuate based on driving conditions such as speed, weight, and route. For example, driving on a smooth highway often yields better mileage than navigating through city traffic. Also, regular maintenance of the vehicle, such as ensuring proper tire pressure and regular oil changes, can help optimize fuel efficiency and save you money on gas in the long run!
