Answer
$26.2\,mi/hr$
Work Step by Step
Angular velocity $\omega=2941\,rpm$
$=\frac{2941\, revolutions}{1\,min}\times\frac{2\pi\,rad}{1\, revolution}\times\frac{60\,min}{1\,hr}$
$=352920\pi\,\frac{rad}{hr}$
Radius $r= 1.5\,in$
$=1.5\,in\times\frac{1\,ft}{12\,in}\times\frac{1\,mi}{5280\,ft}$
Linear velocity $v=r\omega$
$=(352920\pi\,rad/hr)(\frac{1.5}{63360}\,mi)$
$=26.2\,mi/hr$
