The SI base units for length is meter (m) and for time is seconds (s).

The given ratio is
(714 mm)/(37 s)


(714 mm)/(37 s) = 19.297 mm/s \simeq 19.3 mm/s

Converting mm/s to m/s as:

Since, 1 mm/s = 0.001 m/s

So,
19.3 mm/s = 0.0193 m/s

Since, zeroes to the left side of the non-zero number are not significant hence, the evaluation of
(714 mm)/(37 s) to three significant figures and answer in SI units is
0.0193 m/s.
