Answer 2

After 40 hrs it is 213.333 bacterias

Approximately 213 bacterias

Explanation:

Initial population of bacteria is 40

And it doubles every 15 hrs

If 15 hrs is double

1 hrs is 0.13333

Then 10 hrs is 1.3333

So the first 15 hrs

It multiplies to 40*2= 80

The second 15 hrs it multiplies by 80*2=160

The next 10 hrs it multiplies by

160*1.33333= 213.333
