10) Waterlilies

The lake had only one waterlily in the beginning of June. But then it rapidly became covered with waterlilies. The area covered doubled daily. By the end of June, the lake was completely covered.
  1. At what point was half the lake covered with waterlilies?
  2. How long would it take for two waterlilies to completely cover the lake?

Hmmm, no comments. Maybe you scared everyone away with all this math?

Jean: could be. Or it could be that they found it over on Multiply. :-)
