In a lake there is a patch of duck weed, every day the patch doubles in size. If it takes 48 days to cover the pond how long to cover half of it?

I have searched for this and obviously can't find the answer.
Thanks.

If it doubles it size every day then on the 47th day it would be half its size - therefore the answer is 47 days.
