zamiana jednostek :   72 km/h = .... m/s 10 m/s = ..... km/h   prosze o odp z obliczeniami, dzieki.

[latex]72km/h=72cdot frac{1000m}{3600s}=20m/s\ \ 10m/s=10cdot frac{0,001k m}{ frac{1}{3600}h}=36km/h\ \[/latex]

72km/h=72000m/3600s=720m/36s=20m/s 10m/s=10*(¹/₁₀₀₀km/¹/₃₆₀₀m)h=10*³⁶⁰⁰/₁₀₀₀=10*3,6=36km/h
