That would depend on what kind of bacteria you are dealing with and how ideal the environment is for that species.

After t hours the number of bacteria is 10*2t. So 10*2t > 3000000 => 2t > 300000 => t(log2) > log(300000) => t > log(300000)/(log2) => t > 18.19.. So in just over 18 hours (or 18 hours and 12 minutes, approx).
About 10 minutes. It is quite a simple process, with a few different chemicals which you have to flood the bacteria in, and wash off again.
Not much. You could multiply it by 1000000, then it would equal 10 microgram.
Multiply by 10 Answer 100 decimeters
A common bacteria, E.coli, will multiply very fast. For example, an E.Coli will multiply into over a million bacteria in 8 hours.
it depends on the bacteria really because it would be different types but mostly its about 20minutes :) 10 to 20 minutes
If there were b(0) bacteria at the start, there will be b(0)*2^t where after 10*t minutes.
to get hours to minutes you multiply your hours by 3600 and to convert minutes to seconds you multiply your number by 60. . . Multiply your hours number by 60 to convert into minutes Add the original minutes number to the product and then multiply the total minutes by 60 to get the total in seconds. Thus 10 hours and 20 minutes . = 10 x 60 = 600 minutes plus the original 20 minutes then = 620 minutes, . which equals 620 x 60 = 37,200 seconds ( phew !!! )
To convert days to hours, multiply by 24. 10 days X 24 hours = 240 hours. To convert hours to minutes, multiply by 60. 240 hours X 60 minutes = 14,400 minutes.
well there are 24 houres in a day you multiply that by the amount of minuets are in an hour 24X60=1440 then you take that and multiply it by 10% or 0.1 which is 1440X0.1=144 so there are 144 minutes in 10% of a day

You multiply by 60 to have it in minutes. If you have another decimal part, you multiply it by 60 to have it in seconds. Example: If you have 10.33°, then it is the same as 10°19.8', who is the same by the way as 10°19'48''.
Multiply by 10
There's 60 minutes in an hour. Divide 250 by 60 and you get 4.1667 (repeating). You multiply the remainder by 60 and get 10 [minutes]. So the answer is 4 hours and 10 minutes.
I just ChaCha'd the question. They told me that if you have a 64mb of internal memory, Then you can record about 10 minutes. So if we take 64 and multiply it by two then we get 128. So 10 minutes multiply by two equals about 20 minutes .
They can be: 0.7 times 60 = 42 minutes or 7/10 of 60 = 42 minutes
