vlookup

[Trish]

How can I use vlookup to calculate the fuel required for a
flight when it is dependent upon the flying hours, type of
plane, flight distance, and gallons/hour.

A3:A10 contains the planes
B3:B10 contains the trip
C3:C10 contains the flying hours
A15:A18 contains the Planes
B15:B18 contains the Range(miles)
C15:C18 contains the Gallons/hour

I cannot figure out the formula, Please Help Me..
