Answer:
Option 3 - 4 miles
Step-by-step explanation:
Given : In a city, the distance between the library and the police station is 3 miles less than twice the distance between the police station and the fire station. The distance between the library and the police station is 5 miles.
To find : How far apart are the police station and the fire station?
Solution :
Let the distance between police station and fire station be 'x'.
The distance between the library and the police station is 3 miles less than twice the distance between the police station and the fire station.
i.e.
The distance between the library and the police station is 5 miles.
i.e.
Therefore, The police and fire stations is 4 miles apart.
So, Option 3 is correct.

<h3>Area of Compound Shapes</h3>This exercise requires your knowledge about the area of compound shapes. For solving this, you should:
- Identify the basic shapes;
- Calculate your individual areas;
- Sum each area found.
For finding the area, the steps are presented below.
- STEP 1 - Identify the basic shapes.
This trapezoid is composed of two triangles and one rectangle. Therefore, you should sum the area of these geometric figures.
- STEP 2 - Find the area of the triangle.
Area of the triangle - . The figure shows:
b= length of the base= 2in
h=height=9 in
Then,
Note that the triangles are equals, consequently, they present the same values for the area.
- STEP 3 - Find the area of the rectangle.
Area of the rectangle- . The figure shows:
b= length of the base= 12 in
h=height= 9in
Then, .
- STEP 4 - Find the area of the trapezoid.
