2. Last week you were in the unfortunate position of having to drive back to Pittsburg from Concord beginning at 4:30 p.m. You found that every 3 minutes, your speed decreased by 8 miles per hour. It may be helpful to know that Concord is approximately 12 miles from Pittsburg 1. What do you think would be a reasonable starting speed from Concord in light traffic? Explain why you think this is a reasonable choice. b. Make a table comparing the time with your speed. Your first entry will be 4:30 p.m. and the starting speed you picked in part a. c. Graph the values in the table. Clearly label and scale your axes. d. From the table and graph, at what time do you expect to traffic to be at a standstill? 73 e. Find an equation that models this situation. Clearly define your variables. f. Based on the table, graph and equation, at whatrate is your car decelerating? Does this make sense? Which parts of the equation and graph confirm or contradict this answer as your rate of deceleration? 8. Do you think you will make it to Pittsburg before traffic stops? Clearly show and explain all calculations you are using to answer this question 74
