    A girl delivering newspapers cover her route by traveling 2 blocks west, 4 blocks north, then 9 blocks east.
    a) What is her resultant displacement?

    b) What is her direction? Use counterclockwise as the positive angular direction from due east, between the limites of -180 degrees and 180 degrees.

    c)What is the total distance she travels?

    I really need this answer please

    I cannot figure out the displacement either way
    does anyone know what it is?

    I'll tell you that you will need to find the hypotenuse of a triangle.
    If you draw it out, you'll be able to see the triangle. (You'll have to subtract something to see it.)
