Question

5 people fit into a 5x5 foot area. Estimate the size of a crowd that is 5 feet deep and 1 mile long on BOTH sides of the street.​

Answer 1

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;
