7500cm/s = 7500*(1/100m/s)=75m/s 70 km/h = 70*(1000m/3600s)=700/36*m/s=19,(4)m/s 300 m/min= 300*(m/60s)= 5m/s 10 m/s= 10*(1/1000*km/1/3600*h)=360km/h 1800 cm/min= 1800*(1/100m/60s)=3m/s 30 m/s=30*(1/1000*km/1/3600*h)=1080km/h 7 km/h=7*(1000m/3600s)=1,9(4)m/s 8600 cm/s= 8600*(1/100m/s)=86m/s 12 km/h= 12*(1000m/3600s)=3,(3)m/s 19 m/s = 19*(1/1000*km/1/3600*h)=68,4km/h
