Kepler's Law- Jupiter?

I think Sony's answer is correct, but if you'd like me to work this one out on paper and scan it, I can. His explanation is a bit tough to follow, it might just be easier to see how I put the equations together. Its solution will look very much like the one I already did on paper to the last question you asked, that's how I thought of how to apply that solution. Let me know if you need it crunched that way for you.
