Bacteria Growth Rate

  1. 1. The problem statement, all variables and given/known data
    A beaker contained 2000 bacteira. one hour later the beaker contained 2500 bacteria. What is the doubling time of the bacteria?


    2. Relevant equations
    rate = (distance)/(time)
    Time to double = .693/((ln(1+r))^t)


    3. The attempt at a solution
    rate = 2500/2000
    My biggest problem is trying to find the rate, I used this at first, but think it is giving me the wrong answer. I know how to finish the problem, i just need help finding the rate. Thanks!

    You should think in terms of N=N0ekt.
