1000米=1km3600s=1h所以12.5m/s=12.5*(1/1000)km/(1/3600)h=12.5*3.6km/h=45km/h
5m/s等于18km/h5×3600÷1000=18000÷1000=18千米/小时
18km/h=5m/s10m/s=36km/h50cm/s=1.8km/h,20dm/s=7.2km/h
36km=36*1000m=36000m1h=3600s因此36km/h=36000m/3600s=10m/s
120km=120000米120000÷(60×60)≈33.3米120km/h等于33.3米/秒
5,4÷3.6再问:多少再答:1.3再答:1.5再问:嗯再答:是吗再问:嗯,是的
【】1s1m等于1h多少km,即是:m/s,以km/h表示【】m/s=m(x1000/1000)/s=km3600/1000s3666=km3600/1000h=3.6km/h
57.6km/h=(57.6÷3.6)m/s=16m/s
15m/min15m=0.015km,1min=1/60h15m/min=0.015/1/60km/h=0.015*60km/h=0.9km/h
一小时=3600秒所以10m/s=36000m/h=36km/h
20米每秒再问:怎么算的啊再答:72千米等于72000米,一小时等于60分钟等于3600秒,72000÷3600=20(米/秒)
50km/h=50000m/3600s=500m/36s=500000mm/36000ms=500mm/36ms=125/9mm/ms
1800m/h=1.8km/h

407除以3.6就是了113.06

1000km=1000000m1h=3600s1000000m/3600s约等于277.77m/s
3600
1km/h=1000m/h
1000再问:���dz�ѧ�߲�����˼
