Answer:
18.08 minutes.
Explanation:
The formula for getting the doubling time of a bacteria is given by :
Doubling time = ln 2/ specific growth rate.
ln 2 = The natural logarithm of 2.
The specific growth rate = 2.3/h
The the rate is in hours.
Doing the substitution in the formula we have :
ln 2/ 2.3 = 0.6931 / 2.3 = 0.30137
We should remember that the rate was in hours so we need to convert this answer to minutes.
1 hour = 60 minutes
0.30137 × 60 = 18.08 minutes
