Chapter 20:

3. You are a highway patrol officer, seated on a motorcycle, on a curvy section of Highway 2. The

post speed limit is 45 miles per hour on this stretch of the highway. You are monitoring traffic

with a radar gun. The first exit is 4.8 miles up the road. Your radar picks up a speeding car

traveling 66 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 32 seconds after

the speeding car has passed you on the roadside.

A. How fast do you need to go to catch up to the speeding car at the next exit, assuming that

it continues to travel at 66 mph.

B. Illustrate, on a graph, the speed of the speeding car as well as your own motorcycle

during this pursuit.

C. Is your own speed reasonable and safe?
