Question

A certain bacterium can divide every 30 min. If you begin with 1 bacterium, when will you have more than 1,000 bacteria?

Answer 1

`5` hours

Explanation:

`2^9=512`
`2^10=1024`

If a bacterium doubles ever `30` minutes
it will take `10` periods of `30` minutes to grow to more than `1000` bacteria.

`10xx30` minutes `= 5` hours
