Question

Your heart rate is 22 beats for every 20 seconds. Your friend's heart rate is 18 beats for every 15 seconds. Find the heart rates of you and your friend.

Answer 1

The formula for heart rate can be given as :

$Heart rate = \frac{Number of beats}{Time taken }$

Your heart rate is given by:

$Heart rate = \frac{22}{20}$

$Heart rate = \frac{11}{10}$

Your friend's heart rate is given by :

$Heart rate = \frac{18}{15}$

$Heart rate = \frac{6}{5}$

Answer 2

Your heart rate is 22/20 which simplifies to 1.1 beats per second and your friends heart rate is 18/15 which simplifies to 1.2 beats per second
