The cop slows down in order to turn around but must allow cars that are behind him to pass, so before he is able to turn around and begin pursuit, 33 seconds pass. The cop drives down the road A for about 1.6 miles and then executes a right-hand turn onto an alternate road B, executing that turn at about 30 miles per hour. The chase then goes on for another 426 seconds, traveling 8.2 miles before the cop catches up to the speeder. Road B is a winding country road that has 11 curves evenly spaced every .75 miles at which the cop had slow down to 65 miles per hour. What was the top speed that the cop had to reach in order to catch the speeder? Also what was the top speed of the speeder in order to keep the chase going for 426 seconds?
