Answer
1.5 ft/min
Work Step by Step
We know that if point $P$ is a point on a circle of radius $r$, and $P$ moves in a distance $s$ on the circumference of the circle in an amount of time $t$, then the linear velocity, $v$, of $P$ is calculated as $v=\frac{s}{t}$.
We are given that $s=3$ ft and $t=2$ min.
Therefore, $v=\frac{3ft}{2min}=1.5$ ft/min.
