5h= s 50km= 微米 300s= min
1个回答
答:5h=3600s/h×5h=18000 s
50km=50×10^3m=50×10^3×10^6um=5×10^10um=50000000000微米
300s=300s ÷60s/min=5min

1km/min=?km/h=?m/h=?km/s= m/s
(1)1km/h= km/min =m/s (2)8m/s= m/min =km/s
①40cm/s= km/h ②300cm/min= m/s 快啊,22:20之前!

速度单位换算m/s变m/min;km/h变km/min;km/h变km/s;m/s变m/h怎么变?
8m/s=多少km/s 36km/h=多少m/s 30m/min=多少km/s
2.5h=()min=()s 120s=()min=()h
1.2km/min= m/s或 km/h
单位换算:2km= m 10min= s 5min= s
