Question

A fire hose is made of six sections, each 15 feet in length. The sections are joined together with Storz couplings, which are four inches long each. What is the total length of the hose?

Answer 1

Answer:

$h=740\ in$

Explanation:

Given:

length of each pipe section, $l=15\ ft=180\ in$

length of each coupling, $c=4 \ in$

Now according to question we have six hoses which will require 5 couplings to join them.

So the total length of the hose:

$h=6\times l+5\times c$

$h=6\times 180+5\times 4$

$h=740\ in$ is  the total length of the hose.
