Odpowiedź:
s = 40 km = 40000 m
t = 66 min = 3960 s
V = s/t
V = 40000/3960
V = 10,1 m/s
[tex]t = 13^{06} - 12^{00} = 66 \ min = \frac{66}{60} \ h = \frac{11}{10} \ h\\s = 40 \ km\\\\v = \frac{s}{t}\\\\v = \frac{40 \ km}{\frac{11}{10}h} =40\cdot\frac{10}{11} \ \frac{km}{h} = 36,(36)\frac{km}{h}\approx36,36\frac{km}{h}\\\\\boxed{v \approx36,35\frac{km}{h}}[/tex]
