Wyjaśnienie:
a)
[tex]90\frac{km}{h}=90*\frac{1000m}{60min}=\frac{90000m}{60min}=1500\frac{m}{min}[/tex]
b)
[tex]0,3\frac{km}{min}=0,3*\frac{1km}{\frac{1}{60}h }=0,3km*\frac{60}{1h}=18\frac{km}{h}[/tex]
c)
[tex]7,5\frac{dm}{s}=7,5*\frac{10cm}{1s}=75\frac{cm}{s}[/tex]
d)
[tex]14\frac{m}{h}=14*\frac{100cm}{60min}=\frac{1400}{60}\frac{cm}{min}\approx23,3\frac{cm}{min}[/tex]
