A 2-column table with 5 rows. The first column has entries empty, time of trial number 1 (seconds), time of trial number 2 (seconds), time of trial number 3 (seconds), average time (seconds). The second column labeled one quarter checkpoint has entries 2. 15, 2. 05, 02. 02, 02. 7. Use the table to answer the questions. What is the fastest time trial for the first quarter checkpoint? seconds What is the slowest time trial for the first quarter checkpoint? seconds What is the range of times measured for this checkpoint? seconds.
The correct Answer and Explanation is:
To answer the questions based on the given data for the first quarter checkpoint:
1. Fastest time trial:
The fastest time trial is 2.02 seconds (Trial 3).
2. Slowest time trial:
The slowest time trial is 2.15 seconds (Trial 1).
3. Range of times:
To find the range, subtract the fastest time from the slowest:
[
2.15 – 2.02 = 0.13 \text{ seconds}
]
So, the range of times is 0.13 seconds.
Explanation:
- Fastest time: This is simply the minimum value among the three trials, which is 2.02 seconds (Trial 3).
- Slowest time: This is the maximum value among the three trials, which is 2.15 seconds (Trial 1).
- Range: The range of a set of numbers is found by subtracting the smallest number from the largest. In this case, we subtract the fastest time (2.02 seconds) from the slowest time (2.15 seconds) to get 0.13 seconds. This range shows the difference between the best and worst performance during the trials for this checkpoint.
In summary, the fastest trial was 2.02 seconds, the slowest was 2.15 seconds, and the range between them is 0.13 seconds.
