And then I apply the formula.

Twenty miles is a long distance to walk.

Today she arrives at 5 o'clock, and she begins to walk home.

So what's d1? d1 is the distance between this point and this point minus f0.

So it would be the distance around.

Five miles is a long distance to walk.

I am not accustomed to walking long distances.

I exhausted myself by walking a long distance.

It is no less than two hours' walk from here.

I am not accustomed to walking long distances.

These two focal lengths are symmetric.

What's this distance right here? d sub 1.

He is used to walking long distances.

light blue distance?

So if this distance is the same as this distance, then the magenta distance minus this blue distance is going to be equal to this green distance.

I obviously didn't walk there.

The school is within walking distance of my house.

The bus stop is five minutes' walk from here.

It is no more than ten minutes' walk from here.

So it would be that distance plus that distance plus that distance plus that distance.

And we learned that the focus, the focal distance or the distance from the central of the ellipse, which is this distance right here that focal distance is just the square root of the difference of these two numbers.

At a distance of

Distance

That's just this distance right here.

If it's in meters per minute, then this is the distance in meters.

Shark proximity

I'm not accustomed to walking long distances.

So this distance up here is 45vb.

You can see additional adjustments at place at times.

So the first thing to do is figure out what d1 and d2.

Slice distance

But I have a strong feeling he'll be there. ( ominous theme playing ) How far is it?

2200 feet.

How much further?

How far?

Distance.

Distance.

Well, it's joules.

I have a triangle like this.

So we have a simple equation that relates total observed velocity.
