Question

Brads scooter uses 1/4 gallon of fuel each mile. If Brad drives 2 miles. How much fuel does he use?

Answer 1

Brad would use 1/2 gallon of fuel
1/4 per mile × 2 miles= 1/2 gallon of fuel

Answer 2

If 1 mile = 1/4 then you need to double this for 2 miles

1/4 + 1/4 = 1/2

So he uses 1/2 a gallon
