What is the value of $x$ if $|x-1|=|x-2|$ ?

$\mathrm{(A) \ } -\frac12 \qquad \mathrm{(B) \ } \frac12 \qquad \mathrm{(C) \ } 1 \qquad \mathrm{(D) \ } \frac32 {2}\qquad \mathrm{(E) \ } 2$

$|x-1|$ is the same thing as saying the distance between $x$ and $1$ ; $|x-2|$ is the same thing as saying the distance between $x$ and $2$ .

Therefore, $x$ is the same distance from $1$ and $2$ , so $x=\frac{1+2}2=\frac32\Rightarrow\mathrm{(D)}$ .
