问一道初中物理题?

1cm=0.00001km 1h=3600s
所以5cm/s=5*0.00001/(1/3600)km/h=5*0.00001*3600km/h=0.18km/h
不懂就问是一件好事,只有问了弄懂了才会让自己进步!你的这一种精神是值得夸奖的.希望你会不断进步,最后取得好的成绩!只要相信自己,你一定可以的!

=5*3600cm/h=5*36*0.001km/h
接下来你应该知道了吧

1cm=0.00001km
1h=3600s
所以5cm/s=5*0.00001/(1/3600)km/h=5*0.00001*3600km/h=0.18km/h

5cm/s=5cm/1s=(5*10^-5)km/(1/3600)h=0.18km/h

倍数 0.036倍,5乘以0.036=0.18,这么简单还来问,平时少壮不努力老大徒伤悲

5cm/s =(5cm * 1/100000 km/cm) / (1s * 1/3600 s/h)=0.18 km/h

很清楚吧？
