7. an intersection starts getting traffic at
8: 00 am, and then closes for construction
from 1: 00 pm to 2: 30 pm. while the
intersection is open, cars pass through
at a rate of 32 cars each hour. how
many cars pass through the intersection
between 8: 00 am and 5: 00 pm?

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
