Answer:
The time required for the colony to grow two million bacteria is 29.22.
Explanation:
Time required for the colony to grow can be calculated by the following equation:
[tex]t=2log(N/80)/log 2.[/tex]
Here t is time, N = 2 million (require bacteria population).
[tex]t=2log(2,000,000/80)/log2[/tex]
t ≈ 29.22
Time taken by bacteria to grow is 29.22.
