O 3 miles

Answer 1

• C. 4 miles

Explanation:

Let the distance between police station and the fire station be x.

According to question we have:

• 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.

It can be expressed as:

• 5 = 2x - 3

Solve the equation for x:

• 2x = 5 + 3
• 2x = 8
• x = 4

Correct choice is C
