  • Speed is equal to distance over time.

    distance (mi)        time (min)      speed
          2                      10               2/10 = 0.20 mi/min
          4                       20              4/20 = 0.20 mi/min
          6                      45               6/45 = 0.13 mi/min
        10                      50              10/50 = 0.20 mi/min
          8                      60                8/60 = 0.13 mi/min
         11                     60               11/60 = 0.18 mi/min
         12                     70               12/70 = 0.17 mi/min
          15                    90               15/90 = 0.17 mi/min

    Based on the scatter plot, he initially had a speed of 0.20 mi/min but the longer he travels the lower his speed is. His last speed based on the graph is 0.17 mi/min.
