Final answer:
It will take 6 hours for 3 times the original number of bacteria to be present.
Explanation:
To find out how many hours it will take for the bacteria to reach 4 times the original number, we need to determine how many times the original number the bacteria will have to double. Since the bacteria double every 3 hours, we can write an equation:
2n = 4
where n represents the number of times the bacteria doubles.
Solving this equation, we find that n = 2.
Since the bacteria doubles every 3 hours, and it will take 2 doublings to reach 4 times the original number, it will take:
2 * 3 = 6 hours
So, the answer is 6 hours
Your question is incomplete, but most probably your full question was:
If the bacteria in a culture double in 3 hours, how many hours will it take before 3 times the original number is present? It will take__________-- hours. (Answer should be accurate to within' at least three digits.)
