Question

Decide whether the rates are equivalent. 15 breaths for every 36 seconds and 90 breaths for every 3 minutes?

1) True
2) False

Answer 1

Both rates are equal to 30 breaths per minute, so the answer is True. The rates are not equivalent. The first rate is given as 15 breaths for every 36 seconds. We can convert this to breaths per minute by multiplying both the numerator and denominator by 2. The second rate is already in breaths per minute.

Step-by-step explanation:

The rates are not equivalent. To compare the rates, we need to have the same units of time. The first rate is given as 15 breaths for every 36 seconds. We can convert this to breaths per minute by multiplying both the numerator and denominator by 2. For the second rate, 90 breaths for every 3 minutes, we already have breaths per minute. Now we can compare:

15 breaths/36 seconds = 30 breaths/72 seconds = 30 breaths/1.2 minutes

90 breaths/3 minutes = 90 breaths/1.2 minutes

Both rates are equal to 30 breaths per minute, so the answer is True.
