Question

1 . Efectuați transformările :
0.05 hm=
305mm=
205500 cm la a 2 =
20km/h =

Answer 1

0.05 hm = 5 m
305 mm = 0.305 m
205500 cm la 2 = 20.55 m la 2
20km/h = 5.(5) m/s

Answer 2

$0,05 \ hm=5 \ m \\ 305 \ mm=0,305 \ m \\ 205500 \ cm^2=20,55 \ m^2 \\ 20 \ km/h=20 \ 000 \ m/3 \ 600 \ s=5,(5) \ m/s.$
