Question

Liliana takes 4 breaths per 10 seconds during yoga. At this rate, about how many breaths would Liliana take in 2 minutes of yoga?

Answer 1

`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.
