12 km/h=12000m/h=12000m/60min=12000m/3600s=3,(3)m/s
12m/s>3,(3)m/s
12m/s>3,(3)m/s
12 km/h
12 m/s= 12 *60*60= 43200 m/h=43,2 km/h
43,2 km/ h>12 km/h
12 m/s= 12 *60*60= 43200 m/h=43,2 km/h
43,2 km/ h>12 km/h
12km/h < 12m/s ponieważ
12km/h=12*1000m/3600s=3,33m/s
3,33m/s<12m/s
12km/h=12*1000m/3600s=3,33m/s
3,33m/s<12m/s
