Question

In a city, the distance between the library and the police station is 3 miles less than twice the distance between the police

Answer 1

Answer:

Tthe distance between the police station and the fire station  is 4 miles

Step-by-step explanation:

Let's call x the distance between the library and the police station

Let's call z the distance between the police station and the fire station

We know that:

$x = 5$ miles

The distance (x) between the library and the police station is 3 miles less than twice the distance (z) between the police station and the fire station

This is:

$x = 2z-3$

We wish to find the distance z.

Then we equate both equations and solve for the variable z

$5 = 2z -3\\\\2z = 5+3\\\\2z = 8\\\\z =\frac{8}{2}\\\\z = 4\ miles$
