There is 4,194,304 dishes full of bacteria at 10.22, If they keep growing.
Bacterial division, or binary fission, is the process by which a single bacterium divides into two daughter cells. This process occurs when the bacterium grows to a certain size and then replicates its DNA and divides into two separate cells. Binary fission can occur quite rapidly, allowing bacteria to multiply and spread quickly. Some bacteria are able to undergo binary fission in as little as 20 minutes, while others may take several hours.
The dish was half full at 9:30 am and a quarter full at 9:15 am.
At 10:22, if the bacteria continue to grow at the same rate, you would have approximately 2^22 = 4,194,304 dishes full of bacteria.
