Ask Your Question: Enter Your Question and Check Spelling?

Water lilies double in area every 24 hours. In spring, there is one water lily on a lake. In sixty days the lake is completely covered with lilies. How many days did it take to cover half of the lake?

59. It doubles every day, so day 60 it covers the whole lake, one day before (59) it is covering half the lake.
Reply:this question is confusing because there is only one water lily on a lake but in sixty days the lake is completely covered with "lilies." am i on the right track?
Reply:59.
