Final answer:
To find the upper target heart rate zone, add 80% of the maximum heart rate to the resting heart rate.
Step-by-step explanation:
To calculate the upper target heart rate zone, you need to find 80% of the maximum heart rate. In this case, 80% of 197 bpm is 157.6 bpm. To find the upper limit, you add this value to the resting heart rate of 66 bpm. The upper target heart rate zone for this woman is therefore 223.6 bpm.
