Hi I'm new to physic. "What does 'traverse' mean?"

[zm500]

So like Im a junior in high school taking Physic.
In my book, it uses words that I dont understand.
For example, the word 'traverse.'
what does it mean?

[atyy]

It's not a physics word, it means "to move, pass, or go across" (Oxford English Dictionary).

"The question here is, how would Sauron traverse the roughly 50 miles between Barad-dûr and Mt. Doom in time to stop the Ringbearer?" From Sean Crist's http://www.ling.upenn.edu/~kurisuto/eagles.html
