How many times would you have to stop to fill up a 15 mpg gas tank if you are going 360 miles?

To determine how many times you would need to stop to fill up a 15 mpg gas tank on a 360-mile trip, first calculate the total gallons needed. You would need 24 gallons of gas (360 miles ÷ 15 mpg). If your gas tank holds, for example, 12 gallons, you would need to stop once to fill up, as your tank would run out of gas after 180 miles. If your tank holds more than 24 gallons, you would not need to stop at all.
