A:

Answer:240 cars pass through the intersection between 8:00 AM and 5:00 PMStep-by-step explanation:The rate of cars passing = 32 cars each hourThe traffic starts at 8: 00 AM and it goes on till 1:00 PM.So, the number of hours, the traffic flows = 5 hours ..... (1)The intersection is then closed till 2: 30 PMAfter opening, the traffic flows from 2:30 PM to 5 PMSo, the number of hours, the traffic flows = 5 PM - 2: 30 PM hours = 2 . 5 hours ..... (2)So, the Total number of hours traffic flows is = 5 hours + 2 . 5 hours = 7. 5 hoursNow, the cars passing each hour = 32 cars⇒ The cars passing in 7.5 hours = 7.5 x (32 cars) = 240 carsHence, 240 cars pass through the intersection between 8:00 AM and 5:00 PM
