Question 1208792
.


The area of the runway will increase by 100*y  square feet,


and this increment does not depend on x.



=========================



<U>Comment from student</U>: &nbsp;&nbsp;Why does the increment not depend on x?



<U>My response</U>: &nbsp;&nbsp;Extremely stupid question.


You may be surprised, but there is no need to ask "why" - Because it is obvious.



......................................



When a person feigns a desire to solve a math problem, but his brain is sleeping, 
it is an unresolvable internal contradiction of things. These conceptions are not compatible.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;To the next generation of students who will read this post.



The problem in the post is, on the one hand, a joke, and on the other hand, a test.


It is a test to see if a person, who solves it, can immediately grasp the core of the problem 
to solve it with the minimum amount of time and efforts/calculations,

and, in general, to see if the interviewed person is inclined to look for effective thinking/solving.


The other tutors began to make completely unnecessary calculations, determining the area 
of ​​the original runway and the area of the updated runway, and then calculating the difference.


While the simplest calculation is one single multiplication of the width by the increment of the length.


Again, it is a typical test to see if the examinee sees the core of the problem and strives 
to solve it with the least amount of time and efforts, by the most effective way.


When and if you will be in the similar situation on the test, remember this.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Actually, this test is very effective.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Indeed, it produces the outcome instantly;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;from the other side hand, the interviewed person does not even realize 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;and does not even suspect that his hidden qualities are being tested here.
