Answer:
9 pm on a Sunday, 55 .5 days before
Step-by-step explanation:
if there were 6 bacteria initially and from the growth rate we noticed that it doubled every 3 hours
because by 9 am Monday morning there were 5328 bacteria and then by 12 noon (3 hours later), there were 10, 656 bacteria
what we need to know is how long did it take 6 bacteria to become 5328
so
if 6 bacteria = 1 hour
12 bacteria = 3 hours
24 bacteria = 6 hours
then
5328 bacteria = x hours
taking the ratio
we need to now convert this into hours
so we divide by 24
so
9 am 55.5 days before should fall on a Sunday
