This is a linear relationship as the rate of change is constant, ie constant velocity. And the slope represents the velocity, and slope is:
m=(y2-y1)/(x2-x1)
m=(50-25)/(2-1)=25/1
m=25
So the rate of change is 25 mph
Step-by-step explanation:
I have written the answer for you...You must know that diameter is twice the radius.
Steps to solve:
2/3m = 1/2
~Multiply 3/2 to both sides
m = 3/4
Best of Luck!
