Answer:
Mary's target heart rate is 103 beats per minute (bpm).
Explanation:
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.
MHR = 220 - age
So, for Mary: MHR = 220 - 14 = 206 beats per minute (bpm)
Now we can calculate Mary's target heart rate:
Target heart rate = MHR * 50% = 206 * 0.5 = 103 beats per minute (bpm)
