Question

Zamień jednostki prędkości 5m/s= km/min 30cm/h=cm/min 200mm/min=dm/s 30km/s=km/h 100dm/h=m/s

Answer 1

5m/s = 5*0,0001km/(1/60min) = 0,3 km/min

 

30cm/h = 30cm/60min = 0,5 cm/min 

 

200mm/min = 2dm/60s = 0,033 dm/s

 

30km/s = 30km/(1/3600h) = 108 000 km/h

 

100dm/h = 1000cm/3600s = 10m/3600s = 0,00277 m/s ≈ 0,003 m/s
