Question

transforma in sistemul Si :
72km/min
180dm/min
10,8km/min

Answer 1

72×1000m=72000m
1min=60s
72000÷60=1200m/s
180dm=18m
18/60=0,295m/s
10,8×1000=10800m/60s=180m/s

Answer 2

OBS!!!

$\boxed{[V]_{S.I.}=\frac{m}{s}}$


$\frac{72km}{min}=\frac{72.000m}{60s}=\boxed{\frac{1.200m}{s}}$


$\frac{180dm}{min}=\frac{18m}{60s}=\boxed{\frac{0,3m}{s}}$


$\frac{10,8km}{min}=\frac{10.800m}{60s}=\boxed{\frac{180m}{s}}$
