For example, if you started here and you did all this and you came back here, the average velocity would be zero, because you start and end at the same value of x, you get something; 0 divided by time will still be 0.
例如,如果你从这里开始运动,经过这个过程又回到这里,平均速度就是0,因为初态和末态的位移相同,你得到了什么呢,0除以时间还是0
So, you have to imagine that this thing started with these guys back in their camp and the other army back in its camp, and they both have to agree that they want to have a battle, for a battle to take place, and they will have picked a place that is flat where they can do what they're doing.
