Final answer:
The maximum heart rate during a workout varies depending on age. The correct answer is 180 bpm.
Step-by-step explanation:
The maximum heart rate during a workout is measured in beats per minute (bpm). The options provided are 120, 150, 180, and 200 bpm. According to the given information, the maximum heart rate can vary depending on the individual's age. As one ages, the ability to generate maximum heart rates decreases. A general estimation for maximum heart rate can be calculated by subtracting the individual's age from 220 bpm.
For example, a 40-year-old person would have a maximum heart rate of approximately 180 bpm, and a 60-year-old person would have a maximum heart rate of around 160 bpm. Therefore, the correct answer is option 3) 180 bpm.
