Question

A parade route is 1 mile long. People have lined up 5 feet deep on BOTH sides of the street. Using the ratio of 2.5 square feet per person, estimate the number of people in the crowd.
26 people
132,000 people
10,560 people
21,120 people

Answer 1

Answer:

The answer is 21,120 people.

Step-by-step explanation:

There are 5280 feet in 1 mile.

People have lined up 5 feet deep on BOTH sides of the street. So they are lined 10 feet deep combined.

Total lined area = 5280*10

= 52800 square feet

Using the ratio of 2.5 square feet per person,

the number of people in the crowd = 52800/2.5

= 21120

Answer 2

The number of people in the crowd will be 21,120 people

Further Explanation:

Area  

• Area is a measure of how much space is occupied by a given shape.
• Area of a substance is determined by the type of shape in question.

From the question;  

The parade route is 1 mile long.  

People have lined up 5 feet deep on the two sides of the street.  

The ratio is 2.5 square feet per person

Therefore;  

Parade route = 1 mile  

But;  

There are 5280 feet in 1 mile

1 mile = 5280 m  

Hence;

Parade route = 5280 m  

People have lined up 5 feet deep on both sides of the street, therefore;  

They are lined 10 feet deep

Total lined area = Length of the parade multiplied by the width lined up

Thus;  

Total line up area = 5280 ft x 10 ft  

                           = 52800 square feet

But;  

The ratio is 2.5 square feet per person,

Hence;

The number of people in the crowd =The total lined up area divided by the ratio per person

                                                       = 52800/2.5  

                                                       = 21,120 people
