Cheryl runs a race on a 400.0 m circular track. She starts running east of the starting line and then circles the track and falls, stopping 1.00 m west of the starting line. Her time is 80.0 s. What was her average velocity?
I believe that it would be -1.25 x 10^-2 m/s, is this right?

    She started "east" of the starting line. How far east?

    If 0m east, she ran 399m/80s = 4.9875m/s

    don't know where you got the negative velocity, unless you're calculating her falling speed. :-)
