The population of a bacteria sample doubles every 6 hours. How long would it take for the population to triple?
seraphim [82]

The way to solve this question is to essentially reverse the equation I used in the other answer.


I would solve this with some theoretical values. If you start with 3, how long would it take for it to triple, or reach 9.


the equation would look like 9 = 3(2)^t/6, note how the instead of 1/2 it is now 2 in the parenthesis, as it doubles every 6 hours rather than halves every amount of hours.


When placed into an algebra calculator, the answer should be about 9.5 hours
