Mam dwa zadania z matematyki :
1. Oblicz ile to kilometrów na godzinę :
a)v=12m/s
b)v=20m/s
c)v=8m/s
2.Oblicz ile to metrów na sekundę
a)300km/h
b)120km/h
c)80km/h

Zad.1
a) V=12m/s=720m/min=43200m/h=43,2km/h
b) V=20m/s=0,02km/s=1,2km/min=72km/h
c) V=8m/s=0,008km/s=0,48km/min=28,8kkm/h
Zad.2
a) 300km/h=300000m/h=5000m/min=83,(3)m/s
b) 120km/h=120000m/h=2000m/min=33,(3)m/s
c) 80km/h=80000m/h=1333,(30)m/min=22,(2)m/s
1.
a) v= 12m/s
v= 360m/30s
v= 720m/min
v= 43200m/h
v= 43,2 km/h
b) v= 20m/s
v= 600m/30s
v= 1200m/min
v= 72000m/h
v= 72km/h
c) v= 8m/s
v= 240m/30s
v= 480m/min
v= 28800m/h
v= 28,8km/h
2.
a)300km/h = 5km/min = 2500m/30s = 1250m/15s = 83⅓ m/s
b)120km/h = 2km/min = 1km/30s = 500m/15s = 33⅓ m/s
c)80km/h = 80000m/h = 40000m/30min = 1333⅓m/min = 22,(2)m/s
mam nadzieje że pomogłam ;d
