Answer:

The elevation of the work area is 200 meters below the surface of the ground

Step-by-step explanation:

Let

x -----> the elevation of the work area

y ----> the elevation of a mine equipment room

we know that

The elevation above the surface of the ground is positive

The elevation below the surface of the ground is negative

we have

$y=-40\ m$ ---> is negative because is below the surface of the ground

The work area of the mine is 5 times deeper than the elevation of a mine equipment room

$x=5y$

substitute the value of y

$x=5(-40)=-200\ m$

therefore

The elevation of the work area is 200 meters below the surface of the ground
