d) km/h na m/s
18 km/h
90 km/h
72 km/h

Answer 1

a) km na m
0,8 km = 0,8km*1000 = 800m
1, 4 km = 1,4km*1000 = 1400m
3,8 km = 3,8km*1000 = 3800m

b ) m na km
750 m = 750m/1000 = 0,75km
1685 m = 1685m/1000 = 1,685km
4200 m = 4200m/1000 = 4,2km

c) m/s na km/h
10 m/s = = 36km/h
25 m/s =
15 m/s =

d) km/h na m/s
18 km/h =
90 km/h =
72 km/h =
