Explanation:
Generation time is the time taken for a bacterial cell to divide and produce an offspring. Bacterial cells divide exponentially.
The total number of cells is given as =2n x initial number
[n = number of generations]
So if the total is 8 cells:
8=2n x 2
2n=4
n=2
That means 2 generations have arose
Generation time is given as 
where t=the time taken
if t=1hour and n=2
Generation time =
= 0.5hour
Generation time, g =0.5h, and the rate of generation (growth rate), v is 2 per hour
