$48$ breaths

#### Explanation:

If Liliana takes $4$ breaths every $10$ seconds at a constant rate, then the amount of $x$ breaths per two minutes must be equivalent to $4$ breaths per $10$ seconds.

But before we begin to find $x$ we must convert $2$ minutes into seconds so we obtain the same units.

$2$ min$= 2 \left(60\right)$ sec$= 120$ sec

$\frac{4}{10} = \frac{x}{120}$

$x = \frac{4 \left(120\right)}{10}$

$x = 48$

So Liliana would take about $48$ breaths in $2$ minutes.
