Which conversion factors are used to multiply to 18cm/ s to get meters per minute?
Nimfa-mama [501]

Remark

The short answer is you multiply 0.6 times the cm/s to get m/min.

Solve

Though you didn't ask for it, here's the way it is done. Notice that each set of brackets cancels the units of a set of brackets to the left of the set of brackets you are observing. This is called unit analysis. The answer is given below.

\frac{18 cm}{sec} *[\frac{60 cm}{1 min}] * [\frac{1 m}{100 cm}] = 18*0.6\frac{m}{min}=10.8\frac{m}{min}
