Question

Apartment buildings are required to have a fire extinguisher (extintor de incendios) every 600 feet. If a building has a total of 13,500 feet, how many fire extinguishers are needed?

Answer 1

Given:

Apartment buildings are required to have a fire extinguisher every 600 feet.

Height of building = 13,500 feet

To find:

The number of fire extinguishers are needed.

Solution:

Building needs a fire extinguisher every 600 feet.

Height of building = 13,500 feet

So, required number of fire extinguishers is

`n=\frac{\text{Total height of building}}{600}`

`n=(13500)/(600)`

`n=(135)/(6)`

`n=22.5`

Number of fire extinguishers cannot be negative.

`n\approx 23`

Therefore, 23 number of fire extinguishers are needed.
