If a fire truck is pumping water at a rate of 200 l/min, how long will it take to put out a fire in a room with a floor area of 140m squared

Step-by-step explanation:

step 1

Find the minimum volume of water needed to fight a room with a floor area of 140 m^2

see the attached table to better understand the problem

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

Let

x ----> the floor area in square feet

y ---> minimum volume of water in liters

In this problem the relationship between the variables x and y represent a direct variation

Find the constant of proportionality k

Looking at the table

For x=25, y=39

---->

The equation is

For x=140 m^2

substitute and solve for y

step 2

How long will it take to put out a fire in a room with a floor area of 140 m^2

we know that

The fire truck is pumping water at a rate of 200 L/min

The minimum volume of water needed is 218.4 L

so

Divide the minimum volume of water needed by the rate

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
