I'm doing my bio homework and there is a really difficult question and i googled it and nothing helped... so as my second last result i'm asking you.

There are bacteria that undergo binary fission(split in two) every 20 minutes. If one bacterium were present at 2 pm what time would it be when the population of the bacteria reached 1 million (1 000 000)

HELP PLEASE!!

Isn't that just a simple math problem?

Edit: The bacteria will divide 20 times to reach numbers of over 1 million (1,048,576 to be exact).
20*20=400 minutes, which is 6 hours and 40 minutes.
2 PM+6 hours 40 minutes=8:40 PM

You figure out how many divisions it takes to reach 1 million, 1>2>4>8>16>32>64>128 etc until you reach >1 million, each division takes 20 mins, so divisions x20 /60 (minutes in an hour) tells you how many hours it took. After you know how many hours it took you can extrapolate what time it'd be after 2pm when it reached 1 million.

Karvid told you in post 3, but you should do it yourself, you learn nothing from getting everything on a plate.
