Dane:
s = 9km = 9000m
t = 10min = 600 s = 1/6 h

Szukane:
v = ?

km/min:
v = 9km x 10 min = 90 km/min
[v] = km x min = km/min

km/h:
v = 9km x 1/6h = 1,5 km/h
[v] = km x h = km/h

m/s:
v = 9000m x 600s = 5400000 m/s
[v] = m x s = m/s

No to chyba wszystko ;))

T= 10 min = 600 s = 0,17 h
s= 9 km = 9000 m
V=s/t
V= 9000 m / 600 s = 15 m/s
V= 9 km / 10 min = 0,9 km/min
V= 9 km / 0,17 h = 53 km/h
