Answer
(a) 0.0027 ft/s
(b) 0.0019 mi/h
Work Step by Step
(a) We can convert $5.0~cm/min$ to units of $ft/s$:
$5.0~cm/min\times \frac{1~min}{60~s}\times \frac{1~in}{2.54~cm} \times \frac{1~ft}{12~in} = 0.0027~ft/s$
(b) We can convert $5.0~cm/min$ to units of $mi/h$:
$5.0~cm/min\times \frac{60~min}{1~hr}\times \frac{1~in}{2.54~cm} \times \frac{1~ft}{12~in}\times \frac{1~mi}{5280~ft} = 0.0019~mi/h$
