There is a patch of lily pads on a lake. Every day, the patch grows, doubling in size. If it takes 48 days for the patch to cover the entire lake, how many days would it take for the patch to cover half of the lake?
Answer 47 days
Since the patch doubles every day, the lily pads would cover half of the lake the day before they cover the whole thing, making the answer 47 days.
