Answer:

  • 3 m/s; 2 m/s

Step-by-step explanation:

Use the formula:

  • Speed = distance / time

According to the graph, the distance at 2 seconds is 6 m.

The speed is:

  • s = 6/2 = 3 m/s

Total distance is 12 m between zero and 4 seconds and 12 m between 6 and 12 seconds, there is no movement between 4 and 6 seconds. and total time is 12 seconds.

The average speed is:

  • s = (12 + 12) / 12 = 24 / 12 = 2 m/s
