Answer 1

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.
