Put a batch of eggs in the box. Suppose the number of eggs in the box doubles every minute. An hour later, the box was full. When will there be half a box of eggs in the box? The alternative answers are: A. 15 minutes, B.30 minutes, C.45 minutes and D.59 minutes. A seemingly difficult question, but if you think about it carefully, the answer will come out soon, which is 59 minutes. Because the number of eggs in the box doubles every minute, it only takes 1 minute to get from half a box of eggs to a box of eggs, and 1 hour to get to a box of eggs, which means it takes 59 minutes to get to half a box of eggs.
