Question

based on this information, what does the graph show? student a started before student b. student a started after student b. student a and student b started at the same time.

Explanation:

In a distance - time graph, the starting point on the time - axis indicates when the motion begins. Since the blue line (let's assume it represents Student A) starts at the origin on the time - axis and the red line (Student B) starts later on the time - axis, Student A started before Student B.

Answer:

Student A started before Student B.
