So, if we're trying to figure out the wavelength of a Matsuzaka fastball, we need to consider the velocity first, which is 42 miles per hour.

如果我们尝试计算一个,松阪发出快球的波长，我们首先需要考虑速度，每小时为42英里。

We don't usually do our chemistry calculations in miles per hour, so let's switch that to 42 meters per second, so it's -- sorry, it's 94 miles per hour.

在化学计算中我们很少,用英里每小时，所以我们把它换算为42米每秒，对不起，它是94英里每小时。

Things that I say are going at 50 miles per hour you may say are going at 80.

在我看来速度为每小时 50 英里的物体,在你看来速度可能是每小时 80 英里

So how do we get you from for many of you zero to 60 miles per hour after just 11 weeks, well like many courses here is the course structured around not only lectures for conceptual introductions, but sections, office hours and walkthroughs.

十一周后,很多人每小时都能知道60公里内发生的事情，就像这里的很多课程一样,这个课程不只有概念性的介绍，也包括上机和演练讲座。

except when the car is running at 50 miles per hour and they pour all their money into it and they were wiped out.

只有在汽车以时速50公里前行时才管用,可他们把钱全投到了这个东西上,最后只得破产。

And Timlin who is about 91 miles per hour, Timlin So, why don't you take ten seconds to do that.

我们的继投手之一，能做到91公里每小时，one，of，our，relievers。,你们为什么不再花10秒钟,来做这道题？

Sometimes they give you the speed in miles per hour, kilometers per year, pounds per square foot.

有时候速度的单位是英里/小时,千米/年,英磅/平方米

So, first we have Matsuzaka at 94 miles per hour.

所以，首先我们知道松阪的,投球速度是94公里每小时。

For example, if a car is going on a racetrack and you're seeing it from the top, if the speedometer says 60 miles per hour, you might say it's not accelerating.

例如,如果一辆车在跑道上行驶,你从上面俯视它,如果速率表显示的是60英里每小时,你也许会说它没有在加速

And this is a very fast speed, of course, it's about 700 million miles per hour. So, one way to put that in perspective is to think about how long it takes for a light beam to get from earth to the moon. Does anyone have any guesses? Eight seconds, that sounds good.

当然这是一个非常快的速度，它大约是每小时7亿英里,为了更形象化，我们,看看光从地球到月球,需要多少时间，你们猜猜是多少？,8秒，猜的不错。
