To convert the number of pedestrians per day to pedestrians per hour, you would divide the total number of pedestrians in a day by the number of hours in a day.
There are 24 hours in a day, so:
\[ \text{Pedestrians per hour} = \frac{77,256 \text{ pedestrians per day}}{24 \text{ hours}} \]
Calculating that gives:
\[ \text{Pedestrians per hour} = \frac{77,256}{24} \approx 3,219 \]
So, approximately 3,219 pedestrians per hour.
