[Part 1]

Hello, everyone.

In this video, we are going to talk about speed.

Ok…

Now, there’ two ways to express speed.

There’s..uhhh..the Metric System.

Now, the Metric System, that’s what we use in Korea and that’s what I use in Canada.

But, there’s also the Imperial System.

The Imperial System you might see in the U.S.A. or even England.

Ok…

But first, let’s look at the Metric System.

Alright, so I’m just going to focus on ‘k-m-h’.

And ‘k-m-h’, of course, is “kilometers per hour”.

“kilometers per hour.”

Notice I emphasize the ‘s’.

Ok, you always have to express the ‘s’.

“Kilometers.”

“Kilometers.”

“kilometers per hour.”

Alright, so I just have two examples here cause it’s quite easy.

What is this speed?

Well, “Six kilometers per hour.”

Ok, there’s no ‘s’ here, but you…again, you always have to say the ‘s’.

“Six kilometers per hour.”

And the next speed.

“One hundred twenty-five kilometers per hour.”

Ok, let’s say it a little faster.

“Six kilometers per hour.”

“One hundred twenty-five kilometers per hour.”

Ok, you hear the ‘s’?

“Six kilometers per hour.”

Ok, it’s very difficult, but it’s there.

“Six kilometers per hour.”

“One hundred twenty-five kilometers per hour.”

Alright, so I’ve been using the pronunciation of “kilometers”, but some people might say “kilometers”.

Ok, so both pronunciations are acceptable.

“Kilometers” and “kilometers”.

But more common is “kilometers”.

Ok…

So, let’s look at a few example sentences.

2:13 [Part 2 – Example Sentences #1]

Alright, I have three examples here.

The first one.

“The speed limit is one hundred kilometers per hour.”
“The speed limit is one hundred kilometers per hour.”

The second example.

“The KTX travels three hundred kilometers per hour.”
“The KTX travels three hundred kilometers per hour.”

And the last example.

“The average walking speed is five kilometers per hour.”
“The average walking speed is five kilometers per hour.”

2:58 [Part 3]

Ok, let’s talk about the Imperial System.

Again, the Imperial System is commonly used in America, or you might see it in England, too.

They’re going to use ‘m-p-h’.

Now ‘m-p-h’, of course, “miles per hour”.

Again, we have to say “miles per hour”.

“Miles per hour.”

And “one mile per hour” is equal to, about “one point six kilometers per hour”.

Ok…

So again, this is the Imperial System.

This is the Metric System.

Little bit different.

Ok…

So let’s practice expressing these two.

The first one.

“Ten miles per hour.”

I’ll say it a little faster.

“Ten miles per hour.”

“Ten miles per hour.”

Ok, again, there’s the ‘s’.

“Ten miles per hour.”

And the next one.

“Two hundred and one miles per hour.”

“Two hundred and one miles per hour.”

Be sure to have that ‘s’.

Ok, that’s one of the most common mistakes…uhm…my students make.

They say, “mile per hour.”

“Ten mile per hour.”

Ok, you have to have that ‘s’.

“Ten mile per hour.”

“Two hundred and one miles per hour.”

Alright…

Let’s look at a few examples using ‘miles per hour’.

4:28 [Part 4 – Example Sentences #2]

The first one.

“The car was going one hundred miles per hour.”
“The car was going one hundred miles per hour.”

Ok, the second example.

“The airplane travels six hundred miles per hour.”
“The airplane travels six hundred miles per hour.”

And the last example.

“The speed of sound is seven hundred and sixty-one miles per hour.”
“The speed of sound is seven hundred and sixty-one miles per hour.”

5:09 [Part 5]

Alright, so we learned the Metric System using ‘kilometers per hour’.

And we learned the Imperial System using ‘miles per hour’.

So again…uhhh..depends where you are in the world.

Ahh, some countries…actually most countries use the Metric System these days, but probably, certainly if you’re in the U.S.A., they’re still using the Imperial System.

Alright…

So, that’s it.

I hope you’ve learned how to express speed.

And..uhh, see you next time.
