In a creek, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 60 days for the patch to cover the entire creek, how long would it take for the patch to cover half of the creek?

Well since it doubles in size each day, on the 59th day it must have been half the size as the 60th day.
