From the calculations, the rate of growth of the culture is 2.88.
<h3>What is exponential growth problem?</h3>
We apply the exponential growth problem when there is an exponential increase.
Thus, we have; P =Poe^rt
P = amount at time t
Po = amount originally present
t = time taken
r = rate of growth
1.6 × 10^6 = 16e^4r
1.6 × 10^6/16 = e^4r
1.0 * 10^5 = e^4r
ln 1.0 * 10^5 = ln e^4r
11.5 = 4r
r = 11.5/4
r = 2.88
