A buddy of mine tried the same thing (math in court) using the weight of his SUV, the HP of the engine, and other things to show he couldn't have been speeding at the location the officer said he was.

Result: "Too bad. Pay me."

Like they say in the movies; with law it's what is the truth, and what you can prove. He failed the latter and got a hefty fine.
