Part 1
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 by75 % gives the upper limit.
Find the target heart rate range of a 59-year-old.
To find the target heart rate range of a 59-year-old, we need to subtract their age from 220 and then multiply this difference by 60% and 75%.
1. Subtract the age from 220:
220 - 59 = 161
2. Multiply the difference by 60% and 75%:
Lower limit: 161 * 0.60 = 96.6 beats per minute
Upper limit: 161 * 0.75 = 120.75 beats per minute
Therefore, the target heart rate range for a 59-year-old is approximately 96.6 to 120.75 beats per minute.
