Note that
1 cm = 10⁻² m
1 s = 1/60 min

[tex]18 \, \frac{cm}{s} = (18 \, \frac{cm}{s} )*(10^{-2} \, \frac{m}{cm} )*(60 \, \frac{s}{min} ) = 0.6*18 \, \frac{m}{min} [/tex]

Answer:
The conversion factors used are
100 cm = 1 m
60 s = 1 min



I just took the test and can varify that 1m/100cm and 60s/1min are the correct answer for the multiple choice question.
