Hello friends,

I need a little bit of help here.

I have to solve a puzzle for school and i cant find the answer.

Question is "A scientist is experimenting with bacteria that are one micron in diameter and that reproduce by dividing every minute into two bacteria. At 12:00 PM, she puts a single organism in a container. At precisely 1:00 PM, the container is full. At what time was the container half full?"

Can anyone help me out?

Thank you.
