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(60) sec=120 sec

4/10=x/120

x=(4(120))/10

x=48

So Liliana would take about 48 breaths in 2 minutes.
