Question

Devon's target heart rate zone is 140bpm—177bpm. Julian's target heart rate zone is 148bpm—181bpm. They stop running and take their pulse, and both count the heart rate at 173bpm. If they decrease their heart rates by 20bpm, who will be in his THR zone?

Answer 1

To determine who will be in their target heart rate (THR) zone after decreasing their heart rates by 20bpm, we need to compare the adjusted heart rates with their respective target heart rate zones.

Devon's target heart rate zone: 140bpm - 177bpm
Julian's target heart rate zone: 148bpm - 181bpm

Let's calculate their adjusted heart rates after decreasing by 20bpm:

Devon's adjusted heart rate: 173bpm - 20bpm = 153bpm
Julian's adjusted heart rate: 173bpm - 20bpm = 153bpm

Comparing their adjusted heart rates with their respective target heart rate zones:

Devon's adjusted heart rate (153bpm) is within his target heart rate zone of 140bpm - 177bpm.
Julian's adjusted heart rate (153bpm) is within his target heart rate zone of 148bpm - 181bpm.

Therefore, both Devon and Julian will be in their target heart rate zones after decreasing their heart rates by 20bpm.

Answer 2

20bpm

Step-by-step explanation:

To determine who will be in their target heart rate (THR) zone after decreasing their heart rate by 20bpm, we need to subtract 20 from their current heart rate of 173bpm.

For Devon, 173bpm - 20bpm = 153bpm.

Since Devon's target heart rate zone is 140bpm—p177bpm, and 153bpm is within that range, Devon will still be in his THR zone after decreasing his heart rate by 20bpm.

For Julian, 173bpm - 20bpm = 153bpm.

Since Julian's target heart rate zone is 148bpm—181bpm, and 153bpm is within that range, Julian will still be in his THR zone after decreasing his heart rate by 20bpm.

Therefore, both Devon and Julian will still be in their target heart rate zones after decreasing their heart rates by 20bpm.
