s - 9km = 9000m
t - 3min
Szukane:
v - ?
v = s/t
v = 9000m / 3min = 3000 [tex]\frac{m}{min}[/tex] = 180 [tex]\frac{km}{h}[/tex]
pozdr :)
[tex]dane:\\s = 9 \ km\\t = 3 \ min = \frac{3}{60} \ h = \frac{1}{20} \ h=0,05 \ h\\szukane:\\v = ?\\\\v = \frac{s}{t}\\\\v = \frac{9 km}{0,05 \ h} = 180\frac{km}{h}[/tex]
