1km/min=?km/h=?m/h=?km/s= m/s

问题描述:

1km/min=?km/h=?m/h=?km/s= m/s

1km/min=60km/h=60000m/h=0.0167km/s= 16.7m/s

1km/min=60km/h=60000m/h=60分之1km/s= 3分之50m/s

1km/min=1km/(1/60)h=60km/h=60*10^3m/h=6*10^4m/h
1km/min=1km/60s=1/60(km/s),
1km/min=10^3m/60s=1/6*10^2m/s.

1km/min=60km/h=60000m/h=(1/60)km/s=(100/6)m/s

1km/min=60km/h=60000m/h=1/60km/s(0.0167)= 50/3m/s(16.67)
