strus to ptak , ktory droge 36m potrafi przebiec w czasie 2s.Oblicz predkosc strusia podaj ja w m/min i w k/h

s=36m t=2s   v=s/t v=36m/2s v=18m/s = 1080m/min = 64.8km/h  

s=36m t=2s V=s/t V=36m/2s=18m/s V=18m/s   18m - 1s xm - 60s   x=18m*60s:1s=1080m   18m/s=1080m/min   [latex]18frac{m}{s}=18*frac{0,001km}{frac{1}{3600h}}=64,8frac{km}{h}[/latex]
