Question

What is 3.2 × 10−4 m/h in centimeters per second?
A.
8.889 × 10^−6 cm/s

B.
8.889 × 10^−5 cm/s

C.
1.152 × 10^−5 cm/s

D.
1.152 × 10^−7 cm/s

Answer 1

\[3.2 × 10^{−4} \frac{ m }{ h }|\frac{1 h}{3600 s}|\frac{100 cm}{1 m}=8.889×10^{-6}\frac{cm}{s}\]

Answer 2

\[3.2*10^-4 m/s = 3.2*10^-4 * \frac{ 100cm }{ 3600 }\]
\[= 3.2*10^-4 * \frac{ 1 }{ 36 }cm/s \approx 0.8888....*10^-4 cm/s\]
\[= 8.889*10^-6 cm/s\]


so A
