Answer:
The size of the crowd that is 5 feet deep on both sides of the street along a 2-mile section of a parade route is 42,240 people
Step-by-step explanation:
The number of people that can fit comfortably in a 5 feet by 5 feet area = 10
Therefore;
The ratio of the number of people per unit area = 10/(5 × 5) = 10/25
The area, A, occupied by the crowd = 5 feet × 2 mile × 2
2 miles = 10,560 feet
∴ A = 5 feet × 10,560 feet × 2 = 105,600 ft²
We then have;
[tex]\dfrac{Number \ of \ people}{105,600} =\dfrac{10}{25}[/tex]
[tex]Number \ of \ people = {105,600} \times \dfrac{10}{25} = 42,240 \ people[/tex]
