Question

The veterinarian listens to your cat's heart and counts 30 beats in 15 seconds. what is your cat's heart rate?

Answer 1

`((cancel30^2 " beats")/(cancel15 cancel" seconds"))((60 cancel" seconds")/(1 " minute"))=(120 " beats")/"minute"`

Explanation:

Usually heart rate is measured in `"beats"/"minute"`, and so we can find that by saying:

`((cancel30^2 " beats")/(cancel15 cancel" seconds"))((60 cancel" seconds")/(1 " minute"))=(120 " beats")/"minute"`

By the way, a cat's normal heart rate is between 140 and 220 beats per minute, so this cat's owner should be calling the vet!
