Water lily grows at such a rate that it covers double the surface that it covered the day before. It takes 30 days for a water lily to cover the entire surface of the pond. How long would it take for two water lilies of the same size to cover the entire surface of the same pond?
Can somebody rephrase the question? I'm a bit confused:(
As I understood the 2 Lilies have to cover the same size pond as 1 Lily had to cover.... in this case woudn't the two lilies cover the same area twice as faster???
in other words, suppose we divide the pond area in two halvs and give each half to each lilly ... they should both cover the whole area twice as faster...
Thanks in advance!
