Answer to Problem 11CT

7.92 hours , or 7 hours 55 minutes 12 seconds.

Explanation of Solution

Given:

The population of a certain colony of bacteria doubles every 5 hours.

Calcultion:

Let

  b0 = count of bacteria at 0 hours , or , initially

  bt = count of bacteria at t hours

  y% = rate of growth of bacteria , which is constant

  t = time in hours for the population to get triple

So, count of bacteria after 5 hours is double :

  b5=2b0b5=b0(1+y100)5=2b02=(1+y100)5

Find y :

  2=(1+y100)525=1+y100...................[take roots]y=100(251)

Now , find the time t when the count of bacteria is 3b0 :

  bt=3b0bt=b0(1+y100)t=3b03=(1+100(251)100)tlog3=log(1+251)t..................[take log10 each side]log3=log(2)t5t5log2=log3...............................[logab=bloga]t5=log3log2.....................................[divide each side by log2]t=5log3log2...................................[multiply each side by 5]t=5(0.477)0.301t7.92

So, the time is approximately 7.92 hours , or 7 hours 55 minutes 12 seconds. [1 hour = 60 minutes and 1 minute = 60 seconds]
