Vectors bicyclist problem

  1. Mar 8, 2010 #1
    1. The problem statement, all variables and given/known data

    At one instant a bicyclist is 40.0m due east of a park's flagpole, going due south with a speed of 10.0m/s. Then 30.0s later, the cyuclist is 40.0m due north of the flagpole going due east with a speed of 10.0 m/s. For the cyclist in this 30.0s interval what are the A.) magnitude and B.) direction of the displacement, the C.) magnitude and direction of the average velocity and D.) the magnitude and direction of the average acceleration

    2. Relevant equations

    v=d/t
    a=v2-v1/t

    3. The attempt at a solution
    not sure where to start really

    I am confused here, how can a person due east who's going south end up in the north?
