To analyze the performance of Kimberly and Katrina in terms of jumping jacks completed, we can break down the specific points of comparison:
-
The person that did the most jumping jacks initially before the time started:
- The initial count from both tables is zero since both start at the time (0 minutes) with zero jumping jacks. Therefore, the correct response is Neither.
-
The person doing the most jumping jacks per minute:
-
To find the jumping jacks per minute for each person, we can calculate the rate from the data provided:
-
Kimberly:
- 3 min: 28 JJs → 9.33 JJs/min (28/3)
- 8 min: 58 JJs → 7.25 JJs/min (58/8)
- 12 min: 82 JJs → 6.83 JJs/min (82/12)
- 16 min: 106 JJs → 6.63 JJs/min (106/16)
-
The highest rate for Kimberly is 9.33 JJs/min.
-
Katrina:
- 2 min: 16 JJs → 8 JJs/min (16/2)
- 5 min: 40 JJs → 8 JJs/min (40/5)
- 12 min: 96 JJs → 8 JJs/min (96/12)
- 20 min: 160 JJs → 8 JJs/min (160/20)
-
The rate for Katrina is consistently 8 JJs/min.
-
-
Comparing the highest rates, Kimberly has the highest rate of 9.33 JJs/min. So the response is Kimberly.
-
-
The person showing a proportional relationship between time and # of jumping jacks:
- A proportional relationship means that as time increases, the number of jumping jacks increases at a constant rate.
- Looking at the data points:
- Kimberly does not show a constant increase in the number of jumping jacks per minute.
- Katrina has consistent rates of 8 JJs/min throughout all time intervals, indicating a proportional relationship.
- Therefore, the response is Katrina.
Final responses:
- The person that did the most jumping jacks initially before the time started: Neither
- The person doing the most jumping jacks per minute: Kimberly
- The person showing a proportional relationship between time and # of jumping jacks: Katrina
