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
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
1km/h=1000m/h=1000m/3600s=5/18(m/s)=0.2777777777778m/s
一小时=3600秒所以10m/s=36000m/h=36km/h
分子分母*36003600*5m/3600s=18000m/h=18km/h
1km/h=(1000m)/(3600s)=1/3.6m/s0.0095km/s=0.0095/3.6m/s=0.002639m/s

3.6
1000km=1000000m1h=3600s1000000m/3600s约等于277.77m/s
很高兴为你100km/h=100/3.6=27.777777777778m/s=27.78m/s1m/s=3.6km/h1km/h=1/3.6m/s
43.2*1000/3600=12m/s
1m/s=3.6km/h3.6*40=144所以40m/s=144km/h如果不懂,祝学习愉快!
20km/h=20*1000m/(3600s)=200/36m/s=50/9m/s
答案就是3.96km/h,我没必要抄你顺便说一下计算方法1m/s=3.6km/h
1000/3600=0.27777777777777777777
72km/h=72*1000m/60*60s=20m/s10m/s=36km/h
除以3.6
1km/h=1000m/3600s=5/18m/s90km/s=90*5/18=25m/s
公里换到米处以3.6就行了我初中老师说的很管用
