    Would have to use the displacement formula for that. Subtract initial position from final. He moves along a straight line. SW to NE
    Since he does not move along a straight line, would have to use vectors to solve for this. I guess you could use the Pythagorean Theorem and slove for the third side of the triangle and that would be the displacement.

    You would have to contribute to the forums first.
