Answer:
48
Explanation:
It's given that Ava takes 4 breaths every 10 seconds.
4 breaths : 10 seconds. ...(1)
To solve this, first we need to calculate how many seconds there are in two minutes.
As 60 seconds make up one minute, 120 seconds make up two.
Now, to solve for the number of breaths (x), we just multiply (1) by 12. We do this so that we get 120 seconds on the right side, so the left side will give us the answer we need.
4 × 12 breaths : 10 × 12 seconds
48 breaths : 120 seconds.
So, the final answer would be 48 breaths.
Hope this helps! :D
