Question

A scientist creates a colony of bacteria in a dish. This type of
bacteria duplicates itself per minute
If at 9am the experiment started with a single cell and at 9:13
the dish was half-full, at what time will the dish be full?​

Answer 1

Therefore at 9 : 14 am , dish will be full.

A scientist creates a colony of bacteria in a dish. this type of bacteria duplicate itself per minute. at 9 a.m, experiment started with a single cell and at 9 : 13 am the dish was half full.

To find : at what time will the dish be full ?

solution : it is interesting question.

it has given that a bacterium duplicates itself per minute. means, a bacterium becomes two bacteria every minute.

if 9 : am the dish was half full, so dish will be full just after one minute. i.e., 9 : 14 am dish will be full.

Therefore at 9 : 14 am , dish will be full.

Answer 2

Answer:

Step-by-step explanation:

Cannot be determined. Yes, I get the 12:59 answer. But you didn't say the dish was empty. You didn't say if the bacteria die, nor what rate they grow. If they double by mitosis (splitting in two), it's simply impossible that each of the two has exactly the mass and size of the original immediately prior to the split. You didn't say whether there was a vacuum, a centrifuge, a bunch of tiny fish that eat that bacteria, etc. It's a biology problem, and therefore more complex than a simple math problem.

People who say 12:59 are only correct in the same way that a broken clock tells the correct time twice a day, by total coincidence.
