Your heart rate is the number of beats per minute. What is your heart rate if you count 18 beats in 15 seconds?

Answer 1

Your heart rate would be 72 beats per minute.

To calculate, you can use the formula:
Heart Rate = (Number of beats counted in 15 seconds) x 4

Since 15 seconds is one-fourth (0.25) of a minute, you need to multiply the beats counted by 4 to get the heart rate per minute.

So, Heart Rate = 18 x 4 = 72 beats per minute.
