Answer 1

The heart rate reserve for Sharon is 160

Therefore, option (b) is correct.

Step-by-step explanation:

We know that

Maximum Hear Rate (MHR) can be estimated by the formula

MHR = 220 - the given age

According to the question

Sharon is 20 years old

Thus,

MHR for Sharon = 220 - 20 = 200

Given that the resting heart rate for Sharon is 40

Thus, the heart rate reserve for Sharon = 200 - 40 = 160

Hope this answer is helpful.
