3km= dm= cm;8000mm= m= km 7.1h= min= s;2h15min= s;6min2s= s 换算单位我最不行了
![3km= dm= cm;8000mm= m= km 7.1h= min= s;2h15min= s;6min2s= s](/uploads/image/z/8519851-19-1.jpg?t=3km%3D+dm%3D+cm%3B8000mm%3D+m%3D+km+7.1h%3D+min%3D+s%3B2h15min%3D+s%3B6min2s%3D+s)
3km= 30000dm= 300000cm;8000mm= 8m=0.008 km 7.1h=426 min= 25560s;2h15min= 8100s;6min2s=362 s
3km= dm= cm;8000mm= m= km 7.1h= min= s;2h15min= s;6min2s= s
10dm/s=( )km/h 720km/h=( )cm/s 290dm/s=( )m/s 1.68km/min=( )
(1)1km/h= km/min =m/s (2)8m/s= m/min =km/s
速度单位换算1m/s=?km/h=?dm/s=?m/min=?...
如5km/min= km/h= m/h= km/s= m/s
1km/min=?km/h=?m/h=?km/s= m/s
1.08km/min=?m/s=?km/h
1.2km/min= m/s或 km/h
40m\s=( )km\h 3km\min=( )km\min
(1/2)单位换算:72Km/h=()m/s 1m/s=()m/s 340m/s=()km/h 30cm/min=()m
3km/min=()m/s 60m/min=()km/h
1m/s=-----cm/min 1km/h=----m/min
