Question

Vehicle A averages 19 miles per gallon of gasoline, and Vehicle B averages 37 miles per gallon of gasoline. At these rates, how many more gallons of gasoline does Vehicle A need than Vehicle B to make a 1,406-mile trip?
A) 28
B) 36
C) 38
D) 56
E) 74

Answer 1

Ok, I am here. To start, you should make two equations:

19x = 1406 and 37x = 1406. 

x = 74         and   x = 38

Then, just subtract. 

Vehicle A needs 36 gallons more than Vehicle B.

Answer 2

It needs 36 more gallons than vehicle B.
