Answer:


10.5\:mi/h

Explanation:

It was given that Ana bikes for 5.5 hours.


\Rightarrow t=5.5


She covers a distance of
57.75\:mi


\Rightarrow d=57.75


We calculate the speed as follows


Speed=(Distance)/(Time\:taken)



\Rightarrow Speed=(57.75)/(5.5)



\Rightarrow Speed=10.5\:mi/h


The correct answer is D
