Question

1. If Dr. Sinclair works out at the low end of the target heart range (60%), what would her heart rate be?

2. If Dr. Sinclair works out at the high end of the target range (85%), what would her heart rate be?

Answer 1

At the low end of the target heart range, Dr. Sinclair's heart rate would be 108 bpm. At the high end of the target range, her heart rate would be 153 bpm.

Step-by-step explanation:

The low end of the target heart range is 60% of the maximum heart rate (HR). To calculate Dr. Sinclair's heart rate at this level, we multiply 60% by her maximum HR. Let's assume she is 40 years old, so her maximum HR is approximately 180 beats per minute (bpm).

So, Dr. Sinclair's heart rate at 60% of her maximum HR would be:

Heart rate = 60% of 180 bpm = 0.60 x 180 bpm = 108 bpm.

At the high end of the target range (85% of maximum HR), her heart rate would be:

Heart rate = 85% of 180 bpm = 0.85 x 180 bpm = 153 bpm.
