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!
