If a certain automobile gets between 20 and 24 miles per gallon of gasoline, inclusive, what would be the maximum amount of gasoline, in gallons, this automobile would consume on a trip of 360 miles?
(A) 20.0
(B) 18.0
(C) 16.4
(D) 16.0
(E) 15.0
Here we need to calculate the maximum gasoline required.
Therefore the minimum mileage will give the maximum gasoline required.
i.e. 360/20 = 18 gallons
and 360/24 = 15 gallons.
Hence automobile with 20 miles per gasoline uses 18 gallons of gasoline on a trip of 360 miles.
