Samolot leci z prędkością 100m/s. W jakim czasie pokona 25 km. wynik podaj w km/h
V=100m/s
s=25km=25000m
t=?
V=s/t|*t
s=V*t|:v
t=s/V
t=25000m/100m/s
t=250s
V - prędkość samolotu = 100m/s = 360 km/h
s - droga samolotu = 25 km
s = v * t
t - czas przelotu = s/v = 25km:360km/h = 5/72 h = 3600 * 5/72 = 250s
