Two people are both at Point A. Person 1 walks North at a rate of 783 km/hr. Person 2 walks in any direction at a different speed. Where will they meet?

Person 1 walks really fast.

They will meet at Point A, if they don't change direction during their walks.

Edit:

Or the exact opposite of Point A (The other side on Earth, or whatever Sphere they are on.)

Ride each other

Forgot to mention...if Person 2 walks North or South, then they could meet anywhere along the North-South route.

No matter what direction person 2 runs, they will meet at point A

Point A is one of the possible locations, yes.

But there is more than one possible "point" where they could meet.

Otherside of the earth? like you said above, that makes sense too

Grav · Posted 2003-09-26, 04:34 PM in reply to Grav's post "The Next Math Riddle"

Then the answer would have to be in variables example 3x + y where x and y would be there starting points (why do you guys like to confuse people??) just for the fun of it huh?? O_o

So far none of you have the right answer.

Edit:

Spoke too soon

Grav · Posted 2003-09-26, 04:41 PM in reply to Grav's post "The Next Math Riddle"

The answer is that they wouldn't. At that speed, the first person would fling themself free of Earth's gravity and speed off into deep space. Even if the second person moved in the same direction at a greater speed, they wouldn't meet as their arcs would be different because of the difference in speed.

They will meet at point B, because whenever they meet it can't be considered point A, because if that were true you can't have a starting point and a finishing point be the same thing, it will have to be point A and point B.

Read WW's post...

Blah, 783 km/hr.

Grav · Posted 2003-09-26, 06:13 PM in reply to Grav's post "The Next Math Riddle"

The other answer is that it's impossible to walk at 783km/hr

Grav · 07:45 PM

Because it is two times Light speed and more?

Edit:

I read that as m/s, and I meant Sound Speed...

Grav · Posted 2003-09-26, 06:35 PM in reply to Grav's post "The Next Math Riddle"

No, because it's running.

Grav · Posted 2003-09-26, 06:47 PM in reply to Grav's post "The Next Math Riddle"

783 km/hr isnt anything special...supersonic jets usually travel at 2 or 3 times that...

Grav · Posted 2003-09-26, 07:35 PM in reply to Grav's post "The Next Math Riddle"

I thought walking was defined by constantly having contact with the ground with at least one foot, not by actual speed? Besides, the speed of light is over 1 billion km/h (1,079,252,849), 670,616,630 mph, or mach 904,019.

Grav · Posted 2003-09-26, 07:50 PM in reply to Grav's post "The Next Math Riddle"

If he is walking at that speed, he wouldn't detach from earths gravity, because the definition of walking is having at least 1 foot on the ground at once. If you are floating in space, you are no longer walking.

I like the "you can't walk at that speed" answer best.
