You can put this solution on YOUR website!
The rate is change in distance over change in time . In this case time is on the x axis and distance on the y axis so you would have delta y/delta x or
%28y2-y1%29+%2F+%28x2-x1%29=rate point(x1,y1)=(0,0) point (x2,y2)=(3,288)
%28288-0%29%2F%283-0%29=rate
288yds%2F3min=rate
96 yds/min=rate ANSWER Ed's rate is 96 yds/min
