Displacement HELP PLS!

  1. Sep 6, 2007 #1
    1. The problem statement, all variables and given/known data

    The Psychic Squishy Sounds band is on tour in Texas and now are resting in Houston. They traveled 60.0 miles due south from their first concert to Huntsville. If Huntsville is 80.0 miles due north of Houston, what is their displacement from the first concert to Houston? Use the convention that north is positive, and south is negative.

    2. Relevant equations



    3. The attempt at a solution

    +20 - Houston
    |
    |
    0 - First concert
    |
    |
    |
    |
    -60 - Huntsville


    20-0 = 20miles . What to make sure if this is correct.

    According to the question Huntsville should be north of Houston, but you drew it south of Houston.
