The picture shows the movement of the car in a period of time taken by the flash. The strobe camera flashes every 0.5s, and the body is about.

Don't you see that the long picture in this picture is a paragraph? If you look carefully, you can clearly see that each section is the same length, so you can see that a car takes up about one section, so a section is about 3 meters. If you look closely, there are about two sections between the two cars, so it is about 6 meters. I hope it can be adopted! ! !
