Question

12 people fit comfortably in a 5 feet by 5 feet area. Use this value to estimate the size of a crowd that is 25foet deep on both sides of the street along a 3-mile section of a parade route. (Hint: 1 mile - 5,280 ft)

Answer 1

To solve this question, we will follow the steps below:

First, we will find the ratio

`\text{ratio = }(12)/(5*5)=\text{ }(12)/(25)`

Next is to find the area(A)

a mile = 5280 ft from the question

A = 25 x 5280 x 2 x 3

A = 792 000 sq feet

Size of crowd =

`\text{ size of crowd = 792000 }*(12)/(25)\text{ = 380 160 people}`
