Answer
We can rank the speed measurements from smallest to greatest:
$b \lt a \lt e \lt d \lt c$
Work Step by Step
We can convert each speed to units of m/s.
(a) $55~mi/h \times \frac{1609~m}{1~mi} \times \frac{1~h}{3600~s} = 25~m/s$
(b) $82~km/h \times \frac{1000~m}{1~km} \times \frac{1~h}{3600~s} = 23~m/s$
(c) $33~m/s$
(d) $3.0~cm/ms \times \frac{1~m}{100~cm} \times \frac{1000~ms}{1~s} = 30~m/s$
(e) $1.0~mi/min \times \frac{1609~m}{1~mi} \times \frac{1~min}{60~s} = 27~m/s$
We can rank the speed measurements from smallest to greatest:
$b \lt a \lt e \lt d \lt c$
