Question: In a study on speed control, it was found that the main reasons for regulations were to make traffic flow efficient and to minimize the

In a study on speed control, it was found that the main reasons for regulations were to make traffic flow 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 (yrds)
5	10
10	17
20	27
30	50
40	60
50	100
60	150
70	200

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

Questions
