A certain virus has an average doubling time of 28.5 minutes in the human body.
How long does it take 1 virus to grow to a billion (1E9) viruses?
Time in hours (1 decimal)
2%5E%28t%2F28.5%29+=+10%5E9
:
t%2F28.5*log(2) = 9
t%2F28.5 = 9%2Flog%282%29
t%2F28.5 = 29.9
t = 28.5 * 29.9
t = 852 min
:
852%2F60 = 14.2 hrs
