One way is to set up a proportion:
+matrix%281%2C3%2C+130+%2F+4%2C+%22+=+%22%2C+x+%2F+6.7%29+



---------
Another way, which is basically the same as above but with two distinct steps, is to compute the fuel economy (miles per gallon) of the truck, then figure out how far the truck can travel on 6.7 gallons of diesel fuel:

MPG = 130mi/4gal = 32.5mi/gal

The truck can therefore travel 32.5mi/gal * 6.7gal = 217.75 mi on 6.7 gal of diesel fuel.
