Consider the car-caravan analogy from Section 4 in Chapter 1.
In this problem, assume a propagation speed of 120 km/hr and that each toll booth takes 8 seconds to service a car.
a) Suppose the caravan of 10 cars begins immediately in front of the first toll booth, travels 74 km to a second toll booth, then another 74 km to a third toll booth, and finally stops immediately after the third tool booth. Thus, they travel a total of 148 km. What is the total end-to-end delay?
b) Where is the last car in the caravan after one hour? Your answer must include a distance/specific location, and not only a relative direction.
