Wyjaśnienie:
[tex]48\frac{km}{h}=48*\frac{1000m}{3600s}\approx13,3\frac{m}{s}[/tex]
[tex]1,8\frac{cm}{s}=1,8*\frac{\frac{1}{10}dm }{\frac{1}{60}min }=[\frac{1,8}{10}*\frac{60}{1}]\frac{dm}{min}=10,8\frac{dm}{min}[/tex]
[tex]14000g=1400dag=14kg[/tex]
[tex]0,2m^2=0,2*(10dm*10dm)=0,2*100dm^2=20dm^2[/tex]
