On Earth, is it possible to travel 30 miles due south, 30 miles due west, 30 miles due north and end up right where you started? If so, where do you start?

In your imagination?

Ergot · « **Reply #2 on:** August 09, 2005, 03:35:01 pm »

The poles?

Ding ding!

there's actually a lot more than one possible route. draw a picture and explain.

Ergot · « **Reply #4 on:** August 09, 2005, 03:51:55 pm »

You go in a triangle. I don't want to draw.

Sidoh · « **Reply #5 on:** August 09, 2005, 03:54:29 pm »

Solve the rest of the question though.

There are infinite other ways to do it.

Ergot · « **Reply #6 on:** August 09, 2005, 04:00:17 pm »

Yes, you start at either of Earth's poles.

Sidoh · « **Reply #7 on:** August 09, 2005, 04:02:52 pm »

That's not infinite, it's two.

Besides, either of them wouldn't work. It has to be the North Pole. You can't go any further south if you're at the south pole. It's a physical impossibility.

Ergot · « **Reply #8 on:** August 09, 2005, 04:17:16 pm »

As long as the compass is pointing to north and you head in the S direction, you're going south.

Sidoh · « **Reply #9 on:** August 09, 2005, 04:24:52 pm »

The south pole is the ultimate destination of the direction south. Once you're there, you can't go south any further. It's the end of a line, so to speak.

FINE ! I SURRENDER!

Fine, if you're going to be a jerk about it:

How's that?

Sidoh · « **Reply #12 on:** August 09, 2005, 07:53:46 pm »

Omg that drawing sucks, do it again.

Lol, just kidding. Nice work both of you.

Like I said -- there are ininite solutions. Come up with the other... infinity!

Ok!

1. Load in photoshop
2. Press "rotate"
3. Select a random value
4. Repeat infinity times

Sidoh · « **Reply #14 on:** August 09, 2005, 07:56:22 pm »

There's another way to do it though.

iago · « **Reply #15 on:** August 09, 2005, 08:07:46 pm »

Well, you didn't say what order, so start at the south pole and start by going north

Sidoh · « **Reply #16 on:** August 09, 2005, 08:08:53 pm »

No, there's another way to do it (asside from the triangle method that both you and Ergot mentioned) given the same set of instructions.

Ergot · « **Reply #17 on:** August 09, 2005, 08:27:47 pm »

15s -> 15w -> 15s -> 15w -> 30n !

iago · « **Reply #18 on:** August 09, 2005, 08:31:47 pm »

Oh, stupid me!

Start 30mi north of the South Pole

<edit> Can you go west from the South Pole? You'd just be going in circles :-o

You look like a turtle to me.

iago · « **Reply #20 on:** August 09, 2005, 08:51:19 pm »

I guess you could go far enough north that west would take you in a complete circle after going 30km south. So it would look like:
