1.m/min =m/(60s)
所以m/s变m/min要乘上60
2.km/min=km/(1/60h)=60km/h
所以km/h变km/min要除以60
3.km/s=km/(1/3600h)=3600km/h
所以km/h变km/s要除以3600
4.m/h=m/(3600s)
所以m/s变m/h要乘以3600

1m/s=1m/(1/60min)=60m/min
1km/h=1km/(60min)=1/60km/min
1km/h=1km/(3600S)=1/3600km/s
1m/s=1m/(1/3600h)=3600m/h本回答被提问者采纳

1 m/s=60 m/min
1 km/h=1/60 km/min
1 km/h=1/3600 km/s
1 m/s=3600 m/h
