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.
