Answer:
Number of bacteria cells = 2621440 cells
Explanation:
The generation time of a bacteria specie is the time it takes for a population of bacteria to double in number. The generation time for most common bacteria is quite short, about 20 minutes to 1 hour.
Bacteria reproduce asexually by binary fission, in which the parent cell divides into two to produce two identical daughter cells.
In the given question, the generation time of the bacterial species is 20 minutes.
The time that have passed from between the time the sandwich was packed at 6:00 am to lunch time by 12:00 pm is 6 hours.
Using the given formula in the hint: number of cells = 2^(ab) × C
Where a = number of times per hour the bacteria reproduces; b = number of hours; C = number of bacteria at the start
a = 60 minutes/ 20 minutes = 3; b = 6; C = 10
Number of cells = 2^(3 × 6) × 10
Number of cells = 2621440 cells
