Question

the graph below displays jimmys morning walk to the bus stop one morning. answer true or false for the following statements.
part 1

1. for the first 20 seconds, jimmy was walking away from the house.
2. after the first 20 seconds, jimmy walked at a constant speed for 10 seconds.
3. jimmy did not go back to the house.
4. the bus stop is 80 meters away from his home.

part 2

1. what do the horizontal parts of the graph represent?
2. what is jimmy doing between 70 seconds to 90 seconds?

Explanation:

Step1: Analyze first 20 - seconds

In the first 20 seconds, the distance from the house (assuming the starting - point is the house) is increasing on the graph, so Jimmy is walking away from the house.

Step2: Analyze after 20 seconds

After 20 seconds, the graph is not a straight - line segment for 10 seconds, so Jimmy is not walking at a constant speed for 10 seconds.

Step3: Check if Jimmy goes back

The graph does not show a decrease in distance to 0 (which would mean going back to the house), so Jimmy did not go back to the house.

Step4: Determine bus - stop distance

There is no information on the graph indicating that the bus stop is 80 meters away from his home.

Step5: Analyze horizontal parts

Horizontal parts of a distance - time graph represent no change in distance, i.e., Jimmy is stationary.

Step6: Analyze 70 - 90 seconds

Between 70 and 90 seconds, the distance from the starting - point is increasing, so Jimmy is walking away from the house.

Answer:

1. TRUE
2. FALSE
3. TRUE
4. FALSE

Part 2:

1. Jimmy is stationary.
2. Jimmy is walking away from the house.
