Answer:
240 cars pass through the intersection between 8:00 AM and 5:00 PM
Step-by-step explanation:
The rate of cars passing = 32 cars each hour
The 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 PM
After opening, the traffic flows from 2:30 PM to 5 PM
So, 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 hours
Now, the cars passing each hour = 32 cars
⇒ The cars passing in 7.5 hours = 7.5 x (32 cars)
= 240 cars
Hence, 240 cars pass through the intersection between 8:00 AM and 5:00 PM
