**RailKevin**I watched a Modern Marvels program on television that showed how train locomotives are constructed. During the program, a claim was made that a locomotive can move 1 ton about 200 miles on 1 gallon of fuel ( a recent CSX TV ad claims about 400). In contrast, the program said a truck can move 1 ton about 59 miles on 1 gallon of fuel. I am trying to verify the truck calculations by using data from two recent trips (NY to GA and GA to Ontario), but I fear my algebra is a bit weak.

Trip 1: Distance = 1,158 miles, total weight = 23 tons, total fuel consumed = 146 gallons.

Trip 2: Distance = 1,246 miles, total weight = 32 tons, total fuel consumed = 199 gallons.

The total weight includes the empty weight of the truck and maximum fuel load. If the "tons moved" in the claim means only cargo, then subtract 17 tons from the total weight.

Now, the miles/gallon and gallons/ton are easy enough to figure, but I do not understand how to translate that information into 1 ton moved by 1 gallon of fuel X number of miles. Can anyone here figure this out for me?
