Question 167534: In order to achieve maximum results from aerobic exercise, one should maintain ones heart rate at a certain level. A 45 year 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 beats be?

if the rate needs to be 139%3C=x%3C=157 while exercising...... since this is only a 10 second count , we need to divide each limit by 6 (60/10), in order to have the right pulse limits for 10 seconds. 139/6=23.16 and 157/6=26.16 ------------------------------------------------------------------>so pulse needs to be between 23.16%3C=x%3C=26.16 beats for a 10 second count
