Solution

The following figure represents the information given in the problem on a number line.

On the number line, 1−y is the distance between 1 and y, and y−x is the distance between y and x. If y is exactly halfway between x and 1, then 1−y is equal to y−x; and if y is not halfway between x and 1, then 1−y is not equal to y−x. But y can be any number between x and 1, so the correct answer is Choice D.
