The rough drafts for my first three novels (unpublished) took anywhere from a week to a month, writing during every free moment (which I had a lot of, actually, while I was in high school). The revisions took about a month for each. I think I was still trying to figure this thing out, though, because in the end I think they were still too messy to be publishable. The current novel is a completely different story. It's taken about six months to write the rough draft (there's been a lot of personal stuff going on, though, that led to periods during which I couldn't write at all) while the revisions that I'm currently working on look like they're going to take about two months. The funny thing is that this novel, although taking longer, flows better and is coming together in a way that the others didn't. I don't know if it's just natural growth or if it also has to do with taking more time to think things through. For instance, I'm not as impatient so I don't hesitate like I did before about throwing out scenes and chapters that don't work, or rewriting others.
