Amelia's car used 16 gallons to travel 656 miles. How many gallons of gas would she need to travel 533 miles?

Answer 1

If Amelia's car used 16 gallons to travel 656 miles, then the car's mileage is 656/16 = <<656/16=41>>41 miles per gallon
If the car's mileage is 41 miles per gallon, then Amelia would need 533/41 = <<533/41=13>>13 gallons to travel 533 miles. Answer: \boxed{13}.
