If it requires 9 gallons to drive a 369-mile track, you can divide 369 miles by 9 to receive the distance possible with one gallon (369 miles ÷ 9 = 41 miles)
Divide 205 miles by 41 miles and you receive the amount of times to multiply the gallons needed for 41 miles (205 miles ÷ 41 miles = 5 gallons).
