Odpowiedź:
144 km/min = 240 000 cm/s
360 cm/s = 0,216 km/min
150 m/min = 25 dm/s
Wyjaśnienie:
[tex]1 \ km = 100 \ 000 \ cm\\\\1 \ cm = \frac{1}{100000} \ km\\\\1 m = 10 \ dm\\\\1 \ min = 60 \ s\\\\1 \ s = \frac{1}{60} \ min[/tex]
[tex]144\frac{km}{min} = 144\cdot\frac{100000 \ cm}{60 \ s} = 240 \ 000 \ \frac{cm}{s}\\\\360\frac{cm}{s} = 360\cdot\frac{\frac{1}{100000}km}{\frac{1}{60}min} = 360\cdot0,0006 \ \frac{km}{min} = 0,216 \ \frac{km}{min}\\\\150\frac{m}{min} = 150\cdot\frac{10 \ dm}{60 \ s}=25 \ \frac{dm}{s}[/tex]
