You are a highway patrol officer, seated on a motorcycle, on a curvy section of Highway 1. The posted speed limit is 45 miles per hour on this stretch of highway. You are monitoring traffic with a radar gun. The first exit is 3.6 miles up the road. Your radar picks up a speeding car averaging 68 mph. When you try to start your motorcycle to follow the car, it won’t start. You try again and again, and soon you fear that you won’t be able to catch the speeding car before it can turn off the highway. Finally, your motorcycle starts and you begin your pursuit 30 seconds after the speeding car has passed you on the roadside. How fast do you need to go to catch up to the speeding car? What is your average speed in pursuit? Is your own speed reasonable and safe?

Explain why this is or is not a good location at which to monitor traffic.
