P5. Review the car-caravan analogy in Section 1.4. Assume a propagation speed of 100 km/ hour. a. Suppose the caravan travels 150km, beginning in front of one tollbooth, passing through a second tollbooth, and finishing just after a third tollbooth. What is the end-to-end delay? b. Repeat (a), now assuming that there are eight cars in the caravan instead of ten. P5. Review the car-caravan analogy in Section 1.4. Assume a propagation speed of 100 km/ hour. a.
