# At t = 0, the bacterial cell number is 10,000 cells/mL. At t = 480 minutes, the cell number increased to 320,000 cells/mL. The mean generation time during this exponential growth period, rounded off to the nearest integer, is ________ minutes.

At t = 0, the bacterial cell number is 10,000 cells/mL. At t = 480 minutes, the cell number increased to 320,000 cells/mL. The mean generation time during this exponential growth period, rounded off to the nearest integer, is ________ minutes.

## Answer

<p>\textbf{Answer:} 96 minutes</p> <p>\textbf{Explanation:} The mean generation time can be calculated using the formula:</p> <p><br /> \text{Generation Time} = \frac{\text{Time Interval} (t)}{\text{Number of Generations} (n)}<br />

where

<br /> n = \frac{\log (\text{Final cell count}) - \log (\text{Initial cell count})}{\log 2}<br />
