Question

which graph shows that jim and sally started from the same place, and sally ran at a greater average speed than jim?

Explanation:

Step1: Check starting - point

For them to start from the same place, the graphs should have the same y - intercept (assuming the y - axis represents position and x - axis represents time). In all the graphs, the lines for Jim and Sally seem to start at the same vertical position, so this condition is met for all graphs.

Step2: Check speed

Speed is represented by the slope of the position - time graph. A steeper slope means a greater speed. In Graph B, the line representing Sally is steeper than the line representing Jim, indicating Sally has a greater average speed.

Answer:

B. Graph B
