Need help on graphing velocity graphs

    need urgent help on graphing velocity graphs

    1. The problem statement, all variables and given/known data

    (a) You walk 71.4 m at a speed of 1.22 m/s and then run 71.4 m at a speed of 3.05 m/s along a straight track.

    (b) You walk for 1.16 min at a speed of 1.22 m/s and then run for 1.16 min at 3.05 m/s along a straight track.

    (c) Graph x versus t for both cases and indicate how the average velocity is found on the graph. (Do this on paper. Your instructor may ask you to turn in this graph.)


    2. Relevant equations



    3. The attempt at a solution
    i need help on graphing this for part c. i already graphed 1.16(60) divide by 1.22 on the graph but i don't know how to do the second speed. any help would be apprecieated

    Can you describe where you're getting stuck? You found the time for the first distance... just add the time for the second distance...
