Question 192958: Can someone help me? This is what we're studying this week. I thought I was confused before. I'd appreciate any help, Please.
In order to acheive maximum results from aerobic exercise, one should maintain one's heart rate at a certain level. A twenty-five year old woman with a resting heart rate of 80 beats per minute should keep her heart rate between 149 and 172 beats per minute while exercising. She checks her pulse for 10 sec while exercising. What should the number of beats be? The number of beats in 10 sec should be between_and_ beats. Round to the nearest whole number. After basic math and now algebra that still confuses me :( Thank-you for your help.

----------------------------
149 beats per min is 149/60 beats per second
In 10 seconds that would be 149/6 = 24.8333 beats
-----
172 beats per min is 172/60 beats per second
In 10 seconds that would be 172/6 = 28 2/3 beats
