A bacteria doubles every 30 seconds how many after an hour?
I am not sure how realistic "every 30 seconds" is, but here goes.30 seconds is 1/2 minute, so there are 120 doublings in an hour. The answer, therefore, is 2120, or about 1.3 x 1036. (Assuming the "30 seconds" is realistic, it is not realistic to assume that there will be enough food for the bacterias to double this far.)I am not sure how realistic "every 30 seconds" is, but here goes.30 seconds is 1/2 minute, so there are 120 doublings in an hour.
