Zadanie 1
Wartość prędkości wyrażoną w km/h wyraź w m/s
1 km = 1000m
1 h = 3600 s
1 km/h = 1000 m/3600 s = 5 m/18 s = 0,277(7) m/s ≈ 0,28 m/s
18 km/h = .....
90 km/h = .....
72 km/h = .....
Zadanie 2
Wartość prędkości wyrażoną w m/s wyraź w km/h
1 m = 1/1000 km
1 s = 1/3600 h
1 m/s = (1/1000 km) : (1/3600 h) = 1/1000 km · 3600/1 1/h = 36/10 km/h = 3,6 km/h
10 m/s = .....
25 m/s = .....
330 m/s = .....
