How to draw physical circuit diagram speed!

Drawing circuit diagram can be divided into the following types: 1. Draw circuit diagram by looking at the real object. 2. Draw circuit diagram by looking at the real object and connecting components. 3. Design circuit according to the requirements. 4. Identify the wrong circuit and draw the correct diagram

15. The average speed is the distance divided by time. Then an object accelerates in the first second, stops in the second second, decelerates and accelerates in the third second within 10 seconds. The result is that the distance is 100 m, the displacement is 10 m, but the time is 10 s, so the average speed is 10 m / S? The average speed is 1 m / S? No matter what the distance is, our average speed and speed, It's just emphasized that if he uses uniform speed, it's just the speed. I've figured it out,
