2. Solution Steps

First, we need to find the number of visits between 13:30 and 19:

0. $Visits = 15000 - 1600 = 13400$

Next, we need to calculate the time duration between 13:30 and 19:

5. From 13:30 to 19:30 is 6 hours.

From 19:30 to 19:45 is 15 minutes, which is $15/60 = 0.25$ hours.

So the total time duration is $6 + 0.25 = 6.25$ hours.

Finally, we need to calculate the number of visits per hour. This is the total number of visits divided by the time duration.

$VisitsPerHour = \frac{13400}{6.25}$

$VisitsPerHour = 2144$

3. Final Answer

The number of visits per hour is 2144.
