At the time of Endeavour's launch, NASA says the International Space Station was traveling at a speed of about eight kilometers-per-second, above western Romania.

And then we have c, the speed of light, 2.998 times 10 to the 8 meters per second.

然后我们知道光速等于，2，998乘以10的8次方米每秒。

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。

It's something I throw up has an initial speed of 10 meters per second.

抛出物体的,初速度是10米/秒

So, we can just plug it in. Speed is equal to the distance traveled, which is lambda over the time elapsed, which is 1 over nu. so, we can re-write that as speed is equal to lambda nu times nu, and it turns out typically this is reported in meters per second or nanometers per second.

经过的距离和所花的时间,我们把它们带进来,速度等于经过的距离,也即是lambda除以,所花的时间,通常它的单位,是米每秒或者纳米每秒。

I agree, but I want the speed in meters per second.

我同意,但我希望速度以米每秒为单位
