Calculate the time it will take to increase the cell number from 10^4 CFU/ml to 10^8 CFU/ml assuming a generation time of 1.5 hr.(adsbygoogle = window.adsbygoogle || []).push({});

2=e^ut where t is the generation time...solve for u.

x=xo*e^ut where t is time

For the 1st equation:

ln2=lne(ut)

ln2/t=u

ln2/1.5=u

u=0.46 l/hr

For the 2nd equation:

x-xo=e^ut

ln(x-xo)=lne(ut)

ln(10^8-10^4)/0.46=t

I don't know how to solve the 2nd equation.
