Answer
$|r-29| \ge 1$
Work Step by Step
RECALL:
$|a-b|$ represents the distance between the real numbers $a$ and $b$.
Thus, the distance between $r$ and $29$ is represented by $|r-29|$.
Since the distance is no less than (greater than or equal to) $1$ units, then the required inequality is:
$|r-29| \ge 1$
