Zad 1 a) 10 m/s= 10× (0,001km/(1/3600)h)= 10× (0,001km×3600h)= (0,01×3600) km/h = 36km/h
b) 16 m/s = 16× (0,001km/(1/3600)h)= 16* (0,001km×3600h)= (0,016×3600) km/h= 57,6 km/h
c)50 cm/s= 50× (0,00001km/(1/3600)h)= 16× (0,00001km×3600h)= (0,0005×3600) km/h= 1,8 km/h
d) 13 mm/s= 13× (0,000001km/(1/3600)h)= 13× (0,000001km×3600h)= (0,000013×3600) km/h= 0,0468 km/h
Zad 2
a)30000 km/h= 30000* (1000m/3600s)= 300000m/36s= 8333, (3) m/s
b)880 km/h= 880* (1000m/3600s)= 8800m/36s= 244,(4) m/s
c)20 km/h= 20* (1000m/3600s)= 200m/36s= 5,(5) m/s
d)6 km/h= 6*(1000m/3600s)= 60m/36s= 1,(6) m/s
