Odpowiedź:
e) 36 km/h = 10 m/s
[tex]36\ \frac{km}{h} = 36 * \frac{1000\ m}{3600\ s} = 10 \ \frac{m}{s}[/tex]
f) 20 m/s = 72 km/h
[tex]20\ \frac{m}{s} = 20 * \frac{\frac{1}{1000}\ km}{\frac{1}{3600}\ h} = 20* \frac{1}{1000}\ km * 3600\ \frac{1}{h} = 72\ \frac{km}{h}[/tex]
g) 12 cm/s = 0,12 m/s
[tex]12\ \frac{cm}{s} = 12 * \frac{\frac{1}{100}\ m}{s} = \frac{12}{100}\ \frac{m}{s} = 0,12\ \frac{m}{s}[/tex]
h) 1,8 m/h = 0,0005 m/s
[tex]1,8\ \frac{m}{h} = 1,8 * \frac{m}{3600\ s} = 0,0005\ \frac{m}{s}[/tex]
i) 54 km/h = 15 m/s
[tex]54\ \frac{km}{h} = 54 * \frac{1000\ m}{3600\ s} = 15\ \frac{m}{s}[/tex]
j) 144 km/h = 40 m/s
[tex]144\ \frac{km}{h} = 144 * \frac{1000\ m}{3600/ s} = 40\ \frac{m}{s}[/tex]
k) 25 m/s = 90 km/h
[tex]25\ \frac{m}{s} = 25 * \frac{\frac{1}{1000}\ km}{\frac{1}{3600}\ h} = 25 * \frac{1}{1000}\ km * 3600\ h = 90\ \frac{km}{h}[/tex]
