Answer 1

Odpowiedź:

a)

[tex]10\ \frac{m}{min} = 10 * \frac{\frac{1}{1000}\ km}{\frac{1}{60}\ h} = 10 *\ \frac{60}{1000}\frac{km}{h} = 0,6 \frac{km}{h}[/tex]

b)

[tex]15 \ \frac{km}{h} = 15 * \frac{1000\ m}{60\ min} = 250\ \frac{m}{min}[/tex]

c)

[tex]250\ \frac{cm}{s} = 250 * \frac{\frac{1}{100}\ m}{s} = 25\ \frac{m}{s}[/tex]

d)

[tex]150\ \frac{cm}{s} = 150 * \frac{\frac{1}{100}\ m}{\frac{1}{60}\ min} = 150 * \frac{1}{100}\ m * 60\ min = 90\ \frac{m}{min}[/tex]

e)

[tex]720\ \frac{km}{h} = 720 * \frac{100\ 000\ cm}{3600\ s} = 20\ 000\ \frac{cm}{s}[/tex]

f)

[tex]1,8\ \frac{m}{min} = 1,8 * \frac{\frac{1}{100}\ cm}{\frac{1}{60}\ s} = 1,8 * \frac{60}{100}\ \frac{cm}{s} = 1,08\ \frac{cm}{s}[/tex]
