Question

Before a three-week training session, Jules' best 200-meter dash time was 31.2 seconds. After completing the training, her best time was 27.9 seconds. Calculate the absolute change in Jules' 200-meter dash times.

Answer 1

Jules' absolute change in her 200-meter dash time is -3.3 seconds, meaning her time improved by 3.3 seconds after completing the training.

Step-by-step explanation:

Jules' absolute change in her 200-meter dash time can be calculated by subtracting her initial time from her final time. Her initial time was 31.2 seconds, and her final time was 27.9 seconds. Therefore, the absolute change is 27.9 - 31.2 = -3.3 seconds. Since the question asks for the absolute change, we ignore the negative sign and state that Jules' 200-meter dash time improved by 3.3 seconds after completing the training.
