I went to her car; she was sitting in it alone staring out of the window. I was shocked, he had a place in every single plan of mine, I even found job for both of us, I encouraged her. Thanks. See you! – and she headed straight to the shop. Zeke saw them coming and rode to meet them. ―It has to be heading northeast,‖ Zeke said confidently.

First by far to see her was Prince Telemachus, and straight to the porch he went, mortified.
You're a wonderful conversational companion. Her head don't come off! Of course it doesn't! Where you going wit a head like that?! If it isn't you.

I just hears her now. So I was just on my way to lead her back to the beginning, like you told me. For one moment, I thought you were running to help her. You bet it would! I've just noticed that your lovely jewels are missing. I'd better find 'em, but first, I'm off to take the young lady back to the beginning of the Labyrinth, just like we planned!
I've got a much better plan, Hoggle. It ain't gonna hurt the little lady, is it? Oh, why the concern?
I won't do nothin' to harm her. Oh, come, come, come, Hogbrain!

I'm surprised at you, losing your head over a girl. I ain't lost my head! You don't think a young girl could like a repulsive little scab like you, do you? Well, she did say we was If she ever kisses you, I'll turn you into a prince.
Prince of the Land of Stench! What did you have to go and do a thing like that for?! You mean rescue you? I have sworn with my lifeblood no one shall pass this way without my permission. May we have your permission? Canst thou summon up the very rocks?

It's only a Goblin City! Give me the child. I have been generous, up until now.
But I can be cruel. What have you done that's generous?
Everything that you wanted, I have done! You asked that the child be taken - I took him. You cowered before me - I was frightening. I have reordered time, I have turned the world upside down, and I have done it all for you! I am exhausted from living up to your expectations of me.
I have fought my way here to the castle beyond the goblin city Time So rate is defined as distance divided by time, which is a ratio. Speed is another word that is used for rate. When a problem says that a train is moving at a speed of 40 mph, you can understand this to mean that the train's rate is 40 mph, which means it will travel 40 miles in one hour.
Here are two different ways to approach this problem. Let's start by listing the information given: Speed of Train A: We'll use the notion of relative speed 1 or relative rate in order to express the rates of the two trains in one number that can then be used in the distance formula.
Imagine you're on Train A. You're going 70 mph, so your speed relative to the trees, houses, and other non-moving things outside the train is 70 mph. All of those objects look as if they're going by at 70 mph.

Now imagine you're the engineer and you can see Train B coming toward you - not on the same track, of course! Since Train B is moving 60 mph, it will look as if it's approaching faster than if it were sitting still in the station - a lot faster than the trees and houses appear to be moving. The relative speed of the two trains is the sum of the speeds they are traveling. If you're on either of the trains, this is the speed you appear to be moving when you see the other train.
What if the trains were traveling in the same direction?
Then we'd need to subtract the speed of the slower train from the speed of the faster train, and their relative speed would be 10 mph. At this point we know two of the three unknowns:
