Do rolling hills count as intervals? You go down fast, get half way up, and then crawl up - repeat over and over again.
I have no idea what my speed would be on a flat ride as I have never been on one.

On a century ride, you need to pace yourself. Typically, you don't ride the same pace on a century ride as you do on a speedy 45-mile ride. There are plenty of century plans out there. Do a search here, or go to the library. Selena Yeager has several good books out with century plans. There are others, too.
