Question 1118821
.
<pre>
The distance between the library and the police station, which is 5 miles, is 3 miles less than twice the distance 

between the police station and the fire station. 



Hence, twice the distance between the police station and the fire station is 5+3 = 8 miles,

i.e. the police station and the fire station are  {{{8/2}}} = 4 miles apart.
