Question 1183348
.


Which distance and what absolute measures to find ?



Excuse me,  but after reading your post,  it seems to me that the question is not relevant to the  "given"  part,


equally as the  "given"  part is not relevant to the question.



The most likelihood scenario is that you mistakenly combined the given part of one problem with the question of another problem . . . 


It may happen sometimes,  when a person is sooooo busy copying,  pasting and posting many problems, 

that he  (or she)  even has no time to read what is in the post . . .



Give a rest to yourself.



Also,  it may happen,  when the reading of the post is not a part of a performed procedure,  at all . . .  


For example,  if learning is not your goal,  at all,  and the only measure of your productivity is the number of posted messages . . . 



I can easily imagine a number of other scenarios of the same kind . . .
