Question

One rule of thumb for estimating crowds is that each person occupies 2.3 square feet. Use this value to estimate the size of a crowd that is 8 feet wide on both sides of the street standing along a 4.1-mile section of a parade route.

Answer 1

150,595

Explanation:

First, convert miles to feet:

4.1 mi × (5280 ft/mi) = 21648 ft

The area that the crowd takes up is:

2 × 8 ft × 21648 ft = 346368 ft²

The number of people is:

346368 ft² × (1 person / 2.3 ft²) = 150594.8

Rounding to the nearest integer, there are approximately 150,595 people in the crowd.
