19. Revisiting the tollbooth analogy, given the image below, determine how long will it take for the last auto to pass through the last tollbooth. The speed of each car is 100 km/h, processing delay is stated above each booth, distance between booths is below each segment. 10 seconds 100 Km 12 seconds 15 seconds 7 seconds 150 Km 90 Km a. Write an equation that will compute the answer for this specific example. Use P1, P2, P3, and P4 to represent the processing times, n for the number of cars, and S for the speed. b. How long for the last auto to pass through the last tollbooth? State your answer in minutes and seconds. Answer: 20.
