Answer: b, c, and d
Explanation: I hope this helps :)
The maximum heart rate (MHR) is the rate at which the human heart of a given person reaches the highest demands. At rest, the heart rate is about 60 to 80 beats per minute.
Ther's two ways to calculate the maximum heart rate, the most used method is:
MHR = 220 - age
So, for Mary: MHR = 220 - 14 = 206 <span>beats per minute (bpm)
The second method:
MHR (2) = 217 - (0.85 *age)
For Mary:
</span>MHR (2) = 217 - (0.85 *14) = 205 beats per minute (bpm)
We can conclude that the two methods give approximately the same result, but it can differ if we compare them with an elderly person.
Now we can calculate Mary's target heart rate:
Target heart rate = MHR * 50% = 206 * 0.5 = 103 beats per minute (bpm)
Mary's target heart rate is 103 beats per minute (bpm).
