In a study on speed control, it was found that the main reasons for regulations were to make traffic flow more efficient and to minimize the risk of danger. An area that was focused on  in the study was the distance required to completely stop a vehicle at various speeds . Use the following table to answer the questions.

MPH      Braking Distance

20          20

30          45

40          81

50         133

60         205

80         411

 

Assume MPH is going to be used to predict stopping distance.
