    It says


    A women runs from her home and back,covering a total of 4 miles in 1/2 hours.what is her average speed and average velocity?
    A- 4mi/hr,4mi/hr
    B-8mi/hr,4mi/hr
    C-4mi/hr,0mi/hr
    D-8mi/hr,0mi/hr

    I think its C? :confused:

    average speed is

    total distance traveled/time

    so, 4 miles over 0.5 hours

    4/0.5 = 8

    average velocity is

    total displacement/time

    if she went somewhere and came back to her original spot, her displacement is 0.

    thus

    0/0.5 = 0
