Explanation:
We can say straightaway that
To check this:

To start with:
#B(0) = B_o * 2^(0) = B_o# 
Then:
#B(0.25) = B_o * 2^(0.25/0.25) = 2 B_o# so it is doubling :) 
And:
#B(0.50) = B_o * 2^(0.50/0.25) = 4 B_o# , so it has quadrupled. The pattern is established.
Now, if at time 1.25 hours, there are 40,000 bacteria present, we can say that:
So:
After 2 hours:
