It will take 30 hours for its population to be 2.5 times its original size.

#### Explanation:

Since it doubles every 24 hours, we can write an equation like this:

$\frac{2 x}{2} = \frac{24}{2}$ Now, divide each size by 2 to get x by itself.

So, let's say $x$ was its original size. Let's multiply each size by $2.5$.

$\left(2.5\right) x = 12 \left(2.5\right)$

$2.5 x = 30$

We now have our final answer. It will take 30 hours for its population to be 2.5 times its original size :)
