przedstaw w km/h. 4 cyfry znaczace     2m/s 8m/s 20m/s 31m/s 10m/s 58m/s 40m/s 17m/s 19m/s 31m/s

[latex]2frac{m}{s} = frac{0,002km}{frac{1}{3600}h} = 0,002km imes frac{3600}{1}h = 7,2frac{km}{h}[/latex]   i tak robimy z każdym   8m/s = 28,8km/h 20m/s = 72km/h 31m/s = 111,6km/h 10m/s = 36km/h 58m/s = 208,8km/h 40m/s = 144km/h 17m/s = 61,2km/h 19m/s = 68,4km/h 31m/s = 111,6km/h     W razie pytań pisz   I hope I helped   Pozdrawiam Marco12 ;)

Aby zamienić [latex]frac ms[/latex] na [latex]frac{km}h[/latex], należy wynik pomnożyć razy [tez]frac{18}{5}[/latex], i wyrazić go w [latex]frac{km}h[/latex]   [latex]2frac ms=2cdot 18:5[frac{km}h]=7,2frac{km}h;[/latex]   [latex]8frac ms=8cdot 18:5[frac{km}h]=28,8frac{km}h;[/latex]   [latex]20frac ms=20cdot 18:5[frac{km}h]=72frac{km}h;[/latex]   [latex]31frac ms=31cdot 18:5[frac{km}h]=111,6frac{km}h;[/latex]   [latex]10frac ms=10cdot 18:5[frac{km}h]=36frac{km}h;[/latex]   [latex]58frac ms=58cdot 18:5[frac{km}h]=208,8frac{km}h;[/latex]   [latex]40frac ms=40cdot 18:5[frac{km}h]=144frac{km}h;[/latex]   [latex]17frac ms=17cdot 18:5[frac{km}h]=61,2frac{km}h;[/latex]   [latex]19frac ms=19cdot 18:5[frac{km}h]=68,4frac{km}h;[/latex]   [latex]31frac ms=31cdot 18:5[frac{km}h]=111,6frac{km}h.[/latex]
