Answer :
To find the maximum heart rate for a 20-year-old person, you can use the formula:
[tex]\[ \text{Maximum Heart Rate (Max HR)} = 220 - \text{age} \][/tex]
Here's how you can solve this step-by-step:
1. Identify the age of the person, which is 20 years old in this case.
2. Use the formula to calculate the maximum heart rate:
[tex]\[ 220 - 20 = 200 \][/tex]
Therefore, the maximum heart rate for a 20-year-old is 200 beats per minute.
The correct answer is B 200.
