You are in charge of modernizing a busy 20 kilometre-long stretch of highway near a large city. The speed limit on there is 90 km/h and residents have been complaining of excessive speeding on the highway, and the police haven't been able to keep up with the problem. Yourjob is to design some speed traps (described below) that can catch speeding drivers and automatically send them speeding tickets. There are existing metal structures like this one placed every 2 kilometres along this stretch of highway (11 of them in total). The city has a large number of smart cameras that can read the license plates of cars and note the exact times (to the second) the cars pass by the cameras. Your plan is to attach one of these cameras to each of the structures mentioned above. The data from the cameras is then transmitted to a computer system that records the exact time of day at which each car passes each camera in a central database. Your goal is to write a very simple program that will use this data to detect cars that exceed the speed limit, so that their owners can be sent speeding tickets. To avoid errors, you want to design the system to only assign speeding tickets to cars that go at least 10% faster than the speed limit. How should your program work? Describe how a computer can analyze the data collected by the cameras and be sure that a car was speeding at some point. (Your explanation should reference a theorem you've studied recently. You're not being asked to actually write computer code, but describe, mostly in words, how the computer would analyze the data above to nd speed ers, and we can be sure of its conclusions.) Here is some sample data you can think about. This is the data collected about two cars (the column headers are their license plates) as they travel down this stretch of highway and pass all the cameras. One if these cars should get a speeding ticket and the other should not. You are not required to discuss this sample data in your solution. It's just to give you something to work with.
