a)
[tex]6km - 1h[/tex]
Zatem 6km
b)
[tex]6km - 60min \\ x - 1min \\ \\ x = \frac{6 \times 1}{60} = \frac{1}{10} = 0.1km[/tex]
Zatem 0,1km=100m
c)
[tex]6km - 3600s \\ x - 30s \\ \\ x = \frac{6 \times 30}{3600} = \frac{1 \times 3}{60} = \frac{3}{60} = \frac{1}{20} km = \\ = 0.05km[/tex]
Zatem 0,05km=50m
