Question

--- Strep throat is caused by Streptococcus bacteria. The amount of bacteria multiplies at a rate of 10^13 per 10^2 hrs. What is the average growth of bacteria per hour?

Answer 1

The equation is pretty straightforward. Basically, if 10^13 bacteria multiplies in 100 hours. We seek to know how many bacteria multiply per hour. So if 10^13 bacteria mulitply in 100 hours Then X bacteria multiply in an hour. Hence X bacteria * 100 hours = 10 ^13 bacteria * 1 hour. X = 10 ^13 * 1 / 100= 10^(13-2) 10^11. Basically, 10^11 bacterias multiply in an hour.
