Question

Evaluate (714 mm )/(37 s ) to three significant figures and express answer in si units using an appropriate prefix.

Answer 1

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

The given ratio is $\frac{714 mm}{37 s}$

$\frac{714 mm}{37 s} = 19.297 mm/s \simeq 19.3 mm/s$

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 $\frac{714 mm}{37 s}$ to three significant figures and answer in SI units is $0.0193 m/s$.
