But, Ms. Milles was right. I just used algebra skills to work out how long it would take to transfer the data from a webserver in Herndon, to its replica (not replicant, that's totally different) here in Tarzana.
Mind you, I had to cudgel my brain pretty hard to get it to work like that... but hey, it finally came up with the answer. (Which is 96 hours, by the way - unless the rate of data transfer changes. But to calculate that and come up with an accurate answer, I'd need to use calculus. My brain has been cudgeled enough for one day.)
