Interactive Problem 152: Growth of Bacteria Populations

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
The generation time of bacteria is the time $ T$ required for them to double the number of cells; among others, $ T$ depends on the quality of the nutrient solution.

Now consider bacteria, that have $ T_1=20$ minutes in a rich nutrient solution and $ T_2=50$ minutes in a poor nutrient solution. Let the initial bacteria population in the poor nutrient solution be ten times bigger than that of the initial population in the rich solution. How long does it take until both populations are equally big?


Answer: minutes (mathematically rounded)
