Two cars travel on the parallel lanes of a two-lane road. The cars’ motions are represented by the position versus time graph shown in the figure. Answer the questions using the times from the graph indicated by letters. At which of the times do the two cars pass each other? ( can someone please explain what the question is asking)

    Looks like car 2 turned around at C and started going backwards. Thus, the cars will meet at D

    I assume the x-axis (the horizontal axis) is time? and the vertical axis is position?

    If so, the graph limits the cars to position along the y-axis. They can move up the axis or down the axis. When they meet at time labeled D, we see car 1 is moving down the axis (smaller y values) and car 2 is still going up. So they are moving in opposite directions
