To determine the truth of the statements, we need to calculate the heart rates (in beats per minute) for both Shen and Adrian using the formula:
\[ \text{Heart Rate} = \frac{\text{Number of Heartbeats}}{\text{Time (in minutes)}} \]
-
Shen's Heart Rate:
- Heartbeats: 192
- Time: 3 minutes
- Heart Rate = \( \frac{192}{3} = 64 \) beats per minute
-
Adrian's Heart Rate:
- Heartbeats: 360
- Time: 5 minutes
- Heart Rate = \( \frac{360}{5} = 72 \) beats per minute
Now, let's evaluate each statement:
-
Shen has a slower heart rate than Adrian.
- False. Shen's heart rate is 64 bpm and Adrian's is 72 bpm.
-
Adrian has a slower heart rate than Shen.
- False. Adrian's heart rate (72 bpm) is higher than Shen's (64 bpm).
-
Shen’s unit heart rate is 64 beats per minute.
- True. Shen's heart rate is indeed 64 bpm.
-
Adrian’s unit heart rate is 72 beats per minute.
- True. Adrian's heart rate is indeed 72 bpm.
-
Adrian’s unit heart rate is 120 beats per minute.
- False. Adrian's heart rate is 72 bpm, not 120 bpm.
Summary of Truth Values:
- Shen has a slower heart rate than Adrian: False
- Adrian has a slower heart rate than Shen: False
- Shen’s unit heart rate is 64 beats per minute: True
- Adrian’s unit heart rate is 72 beats per minute: True
- Adrian’s unit heart rate is 120 beats per minute: False
True Statements:
- Shen’s unit heart rate is 64 beats per minute.
- Adrian’s unit heart rate is 72 beats per minute.
