According to his boots, his net displacement is of course 180 meter, but I know that is not what the (bad) problem designer had in mind

Is this a homework problem?

Also, does this occur on the Earth, or on a plane?

I have no idea. I assume he mans displacement, instead of distance. :S
Is the magnitude of distance the same as displacement?

Hint: 60, 80 and 100 constitute a Pythagorean triple.

Okay, I think I've got it.
It's kinda like figuring out the hypotenuse?

Thanks everyone : )

Displacement means distance between original spot and final spot, "distance traveled" means the length of his entire pathway.
