Final answer:
To determine Sam's maximum heart rate (HRmax), divide his ideal heart rate for fat burning (102 bpm) by 0.50. Sam's HRmax is 204 bpm, which is within the standard range for maximum heart rates.
Step-by-step explanation:
If Sam's ideal heart rate for fat burning is 50% of his maximum heart rate (HRmax) and is 102 beats per minute (bpm), then we can calculate his HRmax by taking the ideal heart rate and dividing it by the percentage that represents his fat burning zone. So, we have 102 bpm as 50% of his HRmax. To find the HRmax, we can set up a simple equation: 102 bpm = 0.50 × HRmax.
By dividing 102 bpm by 0.50, we would find that Sam’s HRmax is 204 bpm. This value falls within the typical range for maximum heart rates, which is normally 200-220 bpm.
