There is this type of leaf that grows on the surface of a pond. It happens that the leaf multiplies every 24 hours. Therefore 1 becomes 2 the next day; then becomes 4 after the second day; becoming 8 the day after and so on and so forth.

Now it has been determined that it takes 40 days to cover up the whole surface of the pond if we start day 1 with one ...[text shortened]... this time with 2 leaves on day 1. How long does it take to cover the entire surface of the pond?

but duckweed is the only surface-ridding plant i know.
