Review the car-caravan analogy in Textbook Section 1.4 and chapter 1 slides around page 50-51. Assume there are eleven cars in the caravan instead of ten and the propagation speed is 100 km/hour and the distance between two successive tollbooths is 100 km. Suppose the caravan travels 300 km, beginning in front of one tollbooth, passing through a second and third tollbooth, and finishing just before a fourth tollbooth. What is the end-to-end delay?
