    Answer: 3 m/s

    Step-by-step explanation:

    1) the instantaneous speed is the slop at t = 6 secs

    2) since its a straight line, the slop of the line is the speed and its constant.

    the slope is approximately 3 m/s.

           1   2  3  4   5  6|  7  8    

                       t = 5    

    So the formula for speed is

         speed = distance/time

                  S = 15/5

                  S = 3 m/s
