Question

Which conversion factors are used to multiply to 18 cm/s to get meters per minute?

Select each correct answer.



1 m100 cm

60 s1 min

1 min60 s

100 cm1 m

Answer 1

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

Answer 2

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


`18 \, (cm)/(s) = (18 \, (cm)/(s) )*(10^(-2) \, (m)/(cm) )*(60 \, (s)/(min) ) = 0.6*18 \, (m)/(min)`

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