zamien na m/s 45km/h 463km/h 50km/h maja być pełne obliczenia  

  45km/h = 45000m/3600s = 12,5m/s 463km/h = 463 000m/3600s = 128,61m/s 50km/h = 50 000m/3600s = 13,89m/s   1km = 1000m 1h = 3600s   ---------------------------------------------------------------------------------------------------- Litterarum radices amarae sunt, fructus iucundiores   Pozdrawiam :)

[latex]1)\ 45frac{km}{h}=45*frac{1000}{3600}frac{m}{s}=45*frac{10}{36}=frac{450}{36}=12,5frac{m}{s}[/latex]   [latex]2)\ 463frac{km}{h}=463*frac{1000}{3600}=463*frac{10}{36}=frac{4630}{36}approx 128,61frac{m}{s}[/latex]   [latex]3)\ 50frac{km}{h}=50*frac{1000}{36}=50*frac{10}{36}=frac{500}{36}approx 13,89frac{m}{s}[/latex]
