产生误差的平均速度是每秒4米。

The average speed for errors was 4 meters per second.

当裁判以每秒两米的速度移动时，裁判做出了正确的判罚。

Correct decisions came when the referees were moving at a speed of about 2 meters per second.

卫星以11.2千米每秒的速度前进可以脱离地球引力，这被称为“逃逸速度”。

Eleven point two kilometers per second, at which satellites can be freed from the gravitation of the earth, is called "escape speed".

So, if we kind of think about the numbers we would need, we would actually need a velocity that approached something that's about 10 to the negative 30 meters per second.

所以如果我们稍微想想，我们需要的数值是多少，我们需要一个,大约为10的负30次方米每秒的速度。

You get 2.18 times 10 to the plus 6 meters per second, 1% which is about 1% of the value of the speed of light.

。18*10^6米每秒，得到的速度大概是光速的。
