in a germfarm the germs increase exponentically that means after every 20 minutes the germs double in quantity.
a) at 12 oclock the germs are 700. how many are they at 15 oclock?
B) how many where they at 10 oclock?
c)Whats the clock when the germs are 1 000 000?
Thanks again guys need a quick answer, Please the whole calculation not only the answers guys. Im in deep ****.
At 15:20 = 716800 germs
At 15:40 = 1433600 germs, so in 20minutes 716800 germs born, divide that by time.
716800/1200=597.333 germs/persec. 1000000-7168000=283200 germs neeeded. So 283200/597.333=474 secs to produce them.
474/60=6mins54secs. So 15:20+6m54secs=
15:26:54 as my answer. Others may see it different, I'm just getting back into things so I hope it helps.
