[tex]Dane:\\v = 80\frac{km}{h}\\t = 10 \ min = \frac{1}{6} \ h\\Szukane:\\s = ?\\\\s = v\cdot t\\\\s = 80\frac{km}{h} \cdot\frac{1}{6} \ h\\\\\boxed{s\approx13,333 \ km \approx13 \ 333 \ m}[/tex]

[tex]Dane:\\s = 2,4 \ km\\t = 10 \ min = \frac{1}{6} \ h\\Szukane:\\v = ?\\\\v = \frac{s}{t}\\\\v = \frac{2,4 \ km}{\frac{1}{6} \ h} = 14,4\frac{km}{h}\\\\14,4\frac{km}{h} =14,4:3,6\frac{m}{s} =4\frac{m}{s}[/tex]
[tex]\boxed{v = 14,4\frac{km}{h} = 4\frac{m}{s}}[/tex]
