Garbage cans should be set between buildings A, B, C and D in civilized communities. The locations of these four buildings are as follows. If you are a residential property manager, what do you think?

The following picture is shown:

The distances of A, B, C and D are not required to be equal, but the sum of the distances from A, B, C and D to the trash can is required to be minimum.

It is easy to know from the relationship between the sides of a triangle that it should be based on the straight line where A, B, C and D are located.

If it is placed between A and B, the distance from A to the trash can decreases, but the distance from B, C and D to the trash can increases.

Therefore, only when it is established at the midpoint between B and C, the sum of the distances from the four points to the trash can is the smallest.
