  1. 1.

    An automated cart moves along a straight track aligned with the x-axis. Its position–time graph consists of three continuous linear segments: from (0 s, 0 m) to (6 s, 18 m), a horizontal segment from t = 6 s to t = 10 s at x = 18 m, and a third segment from (10 s, 18 m) to (12 s, 6 m). What are the cart's average velocity and average speed over the entire 12-second interval?

    • A) Average velocity is +0.5 m/s, and average speed is 2.5 m/s.
    • B) Average velocity is +2.5 m/s, and average speed is 2.5 m/s.
    • C) Average velocity is +0.5 m/s, and average speed is 0.5 m/s.
    • D) Average velocity is -1.0 m/s, and average speed is 2.0 m/s.
