Answer: 65 miles per hour
Step-by-step explanation:
We know that the rate of change of a function f(x) from x=a to x=b is given by :-
[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]
Now, the rate of change for the given table is given by :_
[tex]k=\dfrac{\text{Distance(6)-Distance (4)}}{6-4}\\\\\Rightarrow\ k=\dfrac{390-260}{2}\\\\\Rightarrow\ k=65[/tex]
Hence, the rate of change for the given table is 65 miles per hour.
