The size of the crowd that is 5 feet deep on both sides of the street along a 1-mile section of a parade route is 42,240 people
Explanation:
The number of people that can fit comfortably in a 5 feet by 5 feet area = 5
Therefore;
The ratio of the number of people per unit area = 5/(5 × 5) = 5/25
The area, A, occupied by the crowd = 5 feet × 1 mile × 1
1 miles = 50.230 feet
∴ A = 5 feet × 50.230 feet × 1 = 250.230 ft²
We then have;
