Question

question 14 of 20 which statements best describe the motion of the train? the trains speed increases, starting at 12:30. the train travels a total round - trip distance of 60 km. the train has a constant speed until 11:00 and then stops moving until 12pm. the train accelerates until 11:00, and then the speed becomes constant. bms sci7_unit2_forcemotion_2526

Explanation:

Step1: Analyze the distance - time graph

The slope of a distance - time graph represents speed. The graph shows a straight - line from 9:00 to 11:00, indicating a constant speed. After 11:00, the distance remains the same until 12:00, meaning the train has stopped moving.

Step2: Evaluate each option

• Option 1: There is no indication of acceleration until 11:00 in the graph.
• Option 2: The graph shows a constant - speed phase from 9:00 to 11:00 and then the train stops as the distance doesn't change after 11:00. This option is consistent with the graph.
• Option 3: There is no information about a round - trip distance of 60 km in the graph.
• Option 4: The speed is constant from 9:00 to 11:00, not increasing starting at 12:30.

Answer:

The train has a constant speed until 11:00 and then stops moving until 12 pm.
