A)Zamień na metry i sekundy 5km/h= m/s 120km/h= m/s B/Zamień na kilometry i godziny 5m/s= km/h Obowiązkowo Obliczenia

A) 1 km = 1000 m 1 h = 3600 s 1 km/h = 1000/3600 m/s 5 km/h = 5 * 1000/3600 m/s = 5000/3600 m/s = 50/36 m/s = 25/18 m/s 120 km/h = 120 * 1000/3600 m/s = 120000/3600 m/s = 100/3 m/s B) 1 m = 1/1000 km 1 s = 1/3600 h 1 m/s = 1/1000 km / 1/3600 h = 3600/1000 km/h 5 m/s = 5 * 3600/1000 km/h = 3600/200 km/h = 18 km/h
