Describe the movement of the car (graph 2) during the time interval from t=9 to t=11.

Graph 2 represents the car's movement. In the time interval from t=9 to t=11:

• At t=9, the car is at a distance of 0 km from point A.
• At t=11, the car reaches point B, which is 120 km away from point A.
• The graph shows a straight line with a positive slope between these two points, indicating constant speed.

Therefore, the car traveled from point A to point B at a constant speed during this time interval.

Ответ: Автомобиль ехал из пункта А в пункт Б с постоянной скоростью.
