Let's also say that a team of four has established an estimated velocity of 50 points per week. This looks like about an 80 man-week job.

例如，假设你接手的项目有1000个故事点，一个四人团队的速率大约是每周完成50个故事点，这就相当于80人周的工作量。

the position of the highest point P we first ask ourselves the question from equation number four: 0 when is the velocity in the y direction zero?

为了找到最高点P的所在,我们首先得,解答我们刚才提出的问题：,究竟何时y方向上的速度减为？

Now, I would think that it is reasonable to ask the following question: What is the average velocity, for instance, between time zero and time four?

现在，我认为,提出如下问题,是十分合理的：,比如说，平均速度是多少，在0到4秒之间？
