To calculate the Maximum Heart Rate (MHR) for a 15-year-old, you can use the formula:
[tex]\[ \text{Maximum Heart Rate} = 220 - \text{age} \][/tex]
Let's go step-by-step through the calculation:
1. Identify the age of the individual. In this case, the age is 15 years.
2. Subtract the age from the number 220:
[tex]\[ \text{Maximum Heart Rate} = 220 - 15 \][/tex]
3. Perform the subtraction:
[tex]\[ 220 - 15 = 205 \][/tex]
Therefore, the Maximum Heart Rate for a 15-year-old is 205 beats per minute.
Given the choices:
- 235
- 205
- 105
The correct answer is 205.
