Answer:

#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.
