Stopping Distances

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 tables to answer the questions.

MPH	BRAKING DISTANCES (FEET)
20	20
30	45
40	81
50	133
60	205
80	411
