How many bacteria will there be after four hours from a single bacterium that divides to produce two cells every 15 minutes

According to the question, a single bacterium will divide into new cells every 15minutes. Since there are four 15 minutes in one hour, which is 60 minutes, a single bacterium will have divided (4×60/15) times =

= 240/15

= 16 times.

Since a single bacterium will divide 16 times in four hours cells, then in four hours, a single bacterium will have divided into 2^16 = 65536 new cells.

Note that, the number of cells a bacterium cell that will divide in two can be expressed as 2^n where n is the number of times

If a bacterium divides into 2 every 15 minutes, there would be 65536 bacteria after four hours.

The bacterium divides into 2 every 15 minutes. Thus, the cell will divide:

60/15 x 4 = 16 times in 4 hours

Thus:

First division = 2 cells
Second division = 4 cells
Third division = 8 cells
Fourth = 16 cells
Fifth = 32 cells
Sixth = 64
Seventh = 128
Eighth = 256
Ninth = 512
Tenth = 1024
Eleventh = 2048
Twelfth = 4096
Thirteenth = 8192
Fourteenth = 16384
Fifteenth = 32768
Sixteenth = 65536
