Question

A crowd of people stood on both sides of the street to view a 4th of July Parade.

The length of the parade was 3 miles long and 15 feet deep on each side of the street.
If 5 people can fit into a 25 ft^2 area.
Estimate the size of the crowd.
(1mile = 5280ft)

Answer 1

Given :

Length of parade ,
`L = 3\ miles=3* 5280\ miles = 15840\ miles` .

Breadth of parade ,
`B=2* 15=30\ ft` .

5 people can fit into a
`25\ ft^2` area.

1 mile = 5280 ft .

To Find :

The size of the crowd.

Solution :

Area of parade ,

`A=15840* 30\ ft^2\\\\A=475200\ ft^2`

Also , 5 people can fit in
`25\ ft^2` area .

So , number of people fit in A is :

`n = (475200* 5)/(25)\\\\n=95040`

Therefore , 95040 can fit in the parade .

Hence , this the required solution .
