You can put this solution on YOUR website! In order to achieve maximum results from aerobic exercise, one should maintain one’s heart rate at a certain level, A 45-yr-old woman with a resting heart rate of 85 beats per minute should keep her heart rate between 139 and 157 beats per minute while exercising. She checks her pulse for 10 sec while exercising. What should the number of the beats be?
-----------
x/10 sec = 139/60 sec
x = (1/6)*139 = 23.167 beats
----
x/10 = 157/60
x = (1/6)*157 = 26.167 beats
-------------------
Her numbers for 10 seconds should be between 23 and 26.
The number of the beats in 10 sec should be between? and ? beats.
