bacteria problem
25 Aug 2006 01:30 pmHave not done any maths since first year. My skills are severely rusted ==;;; Someone tell me whether there's a way in which the following are all satisfied?
1) If you wear earplugs for an hour, the bacteria in your ear increase 700 times.
2) The doubling time of Staphylococcus under optimal conditions is approximately 30 minutes. Doubling time of Streptococcus is approximately 25 minutes. These two bacteria predominate in the ear canal.
3) Assuming that without earplugs, in normal conditions, the amount of bacteria in your ear should remain constant, and that the bacteria are already in stationary phase (i.e. the growth rate is constant).
