Answer 1

Answer:

water lilies double in an area every 24 hours. In spring, there is one water lily on a lake. In 60 days the lake is completely covered with lilies. How many days did it take to cover half of the lake?

Step-by-step explanation:

water lilies double = 24 hours

starte                      = 1 lily

60th days                  = completely covered with lilies

so, it takes to cover half of the lake = 59 days

since it doubles every 24 hours,

on 59th day the lake is filled half part, when comes to 60th day its covers full lake

so the solution is 59 days
