If one year was a foot then 65 million years will be 65 million feet. 1 mile=5280 feet so.
65 million divided by 5280= 12310.6
So your answer would be 12,310 miles.
Every action has an equal and opposite reaction. I would assume that the energy in the other direction would be an action.. though I'm not entirely sure. I hope it helps.
According to the second law of thermodynamics, energy is never 100% efficient because some of the energy disperses as heat.
