A cell divides every minute. It will fill a 100 ml. beaker in one hour. How much time would it take to fill 50 ml. beaker? Please explain the answer.

A cell divides every minute and doubles its number. Suppose 300 cells can fill a 100 ml beaker, then 150 cells can fill a 50 ml beaker.
tThe cell took One hour i.e. 60 minutes to fill a 100 ml beaker. Thus,  as the cells double their number in every one minute, there must have been  formed 150 cells in the 59 minutes which divided in the  next one minute to become 300 in number and completely filled  the 100 ml beaker.
Thus, it becomes clear that a 50 ml beaker will be filled in 59 minutes.
