To identify the mistakes Albert has made in his distance-time graph based on the given list of "Possible mistakes," here is the analysis:

Observed Mistakes:

1. The line should not start at 11:00: The journey starts at 11:00 on the graph, which is incorrect. Realistically, a journey may start before 11:00.
2. The line should end at 4 km: The graph ends at 5 km instead of the correct 4 km. This is clearly a mistake.
3. The horizontal section should be shorter: The graph shows a long horizontal section (between 11:10 and 11:15) where the distance remains constant. This pause is likely too long for a journey to school.
4. Missing units from the time axis: The time axis is missing units (e.g., "minutes" or "hours"), which makes interpretation ambiguous.
5. Missing units from the distance axis: Similarly, the distance axis lacks units (e.g., "km"), which is necessary for clarity.

Final List of Mistakes:

1. The line should not start at 11:00.
2. The line should end at 4 km, not 5 km.
3. The horizontal section should be shorter.
4. Missing units from the time axis.
5. Missing units from the distance axis.

Would you like me to explain why each mistake is incorrect in more detail or how to fix the graph?

Tip:

In a distance-time graph, the slope represents speed. A steep slope means fast movement, while a horizontal line indicates the object is stationary.
