To find a person's target heart rate in beats per minute, follow this procedure. Subtract the person's age from 220, then multiply this difference by 60% and 75%. The difference
multiplied by 60% gives the lower limit and the difference multiplied by 75% gives the upper limit.
Find the target heart rate range of a 48-year-old.
To find the target heart rate range for a 48-year-old, follow these steps:
1. Subtract the person's age from 220
220 - 48 = 172
2. Multiply this difference by 60% to find the lower limit:
172 * 0.6 = 103.2
3. Multiply this difference by 75% to find the upper limit:
172 * 0.75 = 129
Therefore, the target heart rate range for a 48-year-old is between 103.2 beats per minute (lower limit) and 129 beats per minute (upper limit).
