Odpowiedź:
8[tex]\frac{km}{h}[/tex] * [tex]\frac{1}{4}[/tex]h = 2 km
22[tex]\frac{km}{h}[/tex] * [tex]\frac{1}{3}[/tex]h = [tex]7\frac{1}3}[/tex] km
35[tex]\frac{km}{h}[/tex] * [tex]\frac{1}{12}[/tex]h = [tex]2\frac{11}{12}[/tex] km
2km + [tex]7\frac{1}3}[/tex] km = [tex]2\frac{11}{12}[/tex] km = 2km + 7[tex]\frac{4}{12}[/tex]km + [tex]2\frac{11}{12}[/tex]km = 2km + [tex]10\frac{2}{12}[/tex]km = [tex]12\frac{2}{12}[/tex]km = [tex]12\frac{1}{6}km[/tex]
Szczegółowe wyjaśnienie:
Pokonał dystans [tex]12\frac{1}{6}km[/tex].
