The average speed is a rough description of how fast an object moving at variable speeds moves at -- or
The standard answers are as follows:
Average speed is a rough description of how fast an object moving at variable speed moves (over a distance) or (over a period of time)
I hope I can help you~~
The average speed can describe the speed of variable speed motion
2. In variable speed linear motion, the ratio of a distance to the -------- used to pass the distance is the average speed of the distance. Help me solve these two problems,
In variable speed linear motion, the ratio of a distance to the time taken to pass the distance is the average speed of the distance
It is used to describe the average distance of a certain distance (or a certain period of time) outside an object moving in a variable speed linear motion____ The calculation formula is____
Speed x displacement / time t
