54km/h=( )m/s
5m/s=( )km/h
300cm/min=( )m/s
54km/h=( )m/s
5m/s=( )km/h
300cm/min=( )m/s
想知道答案是没用的 你不应该来这里要“鱼" 应该去学会“渔”
1.54km/h=54*1000m/3600s=15m/s
2.5m/s=5÷1000km/1÷3600s=18km/h
3.300cm/min=300÷100m/60s=0.05m/s
54km/h=54000m/3600s=15m/s (km/h化成m/s只需除以3.6)
5m/s=0.005km/(1/3600)h=18km/h (m/s化成km/h只需乘以3.6) 这两个转化要记住
300cm/min=3m/60s=0.05m/s
km化成m乘以5/18,m化成km乘以3.6,15,18,0.05
