Doug records how many miles and how long he rides his bike each day on a scatter plot.

Doug analyzes his data on the scatter plot and concludes that the more time he rides his bike, the slower his speed is. In two or more complete sentences, explain why or why not it is possible for Doug to make his conclusion based on his data.

Step-by-step explanation:

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.

2 is the final ! : )
