Final answer:
The slope from point D to point E on the graph represents Daniel's speed between these two points. The slope is 10 meters per minute.
Step-by-step explanation:
The slope from point D to point E on the graph represents Daniel's speed between these two points. To determine the slope, we need to find the change in position and the change in time between the two points. The slope is calculated by dividing the change in position by the change in time.
Let's assume that the change in position from D to E is 100 meters and the change in time is 10 minutes. The slope would then be 100 meters divided by 10 minutes, which is equal to 10 meters per minute.
Therefore, the correct answer is A) 10; The slope indicates that Daniel's speed is 10 meters per minute.
