![To achieve the maximum benefit for the heart when exercising, the heart rate (in beats per minute) should be in the target heart rate zone. The lower limit of this zone is found by taking 70% of
the difference between 220 and the age of the person. The upper limit is found by using 85% of the difference. Complete parts a through d.
U= 187 - 0.85x (Use integers or decimals for any numbers in the equation. Do not factor.)
L= 154 - 0.7x (Use integers or decimals for any numbers in the equation. Do not factor.)
b. What is the target heart rate zone for a 20-year-old?
For a 20-year-old person, the lower limit is 140 and the upper limit is 170 beats per minute.
c. What is the target heart rate zone for a 60-year-old?
For a 60-year-old person, the lower limit is 112 and the upper limit is 136 beats per minute.
d. Two women in an aerobics class stop to take their pulse and find that they have the same pulse. One woman is 36 years older than the other and is working at the upper limit of her target
heart rate zone. The younger woman is working at the lower limit of her target heart rate zone. What are the ages of the two women, and what is their pulse?
