A student is speeding down Route 11 in his fancy red Porsche when his radar system warns him of an obstacle 400 feet ahead. He immediately applies the brakes, starts to slow down, and spots a skunk in the road directly ahead of him. The "black box" in the Porsche records the car's speed every two seconds, producing the following table. The speed decreases throughout the 10 seconds it takes to stop, although not necessarily at a uniform rate. \begin{tabular}{|c|c|c|c|c|c|c|} \hline Time since brakes applied (sec) & 0 & 2 & 4 & 6 & 8 & 10 \\ \hline Speed (ft/sec) & 120 & 70 & 45 & 25 & 10 & 0 \\ \hline \end{tabular} A. What is your best estimate of the total distance the student's car traveled before coming to rest (note that the best estimate is probably not the over or under estimate that you can most easily find)? distance $=$ $\square$ (include $\square$ help (units) ) B.
