On the surface of a pond one water lily floats, which constantly divides and grows. Thus, the area which water lilies occupy grows two times every day. The whole surface of the pond appears to be covered in 30 days. How long does it take to cover all the surface of the pond if initially, two water lilies float on the surface?

Since one growing lily will cover the whole surface in 30 days, two lilies are the sum obtained after division of one lily on the next day.
