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. how far apart are the police station and the fire station? miles

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:

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:

We wish to find the distance z.

Then we equate both equations and solve for the variable z

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

i think the length is 12 and the width is 17
