0,2 h ile to minut i sekund 1,3h ile to minut i sekund 2,75h ile to minut i sekund   Samochud jechał z szybkością 90km/h. Oblicz ile kilometrów przejechał w ciągu 6 min .   Proszę podać obliczenia xD  

0,2h = 0,2 x 60min = 12min 12min = 12 x 60s = 720s   1,3h = 1,3 x 60min = 78min 78min = 78 x 60s = 4680s   2,75h = 2,75 x 60min = 165min 165min = 165 x 60s = 9900s   6min = 6 : 60 = 0,1h 90km/h x 0,1h = 9km Odp.: W ciągu 6min samochód przejedzie 9km.

0,2h = 12min = 720s 1,3h = 78min = 4680s 2,75h = 165min = 9900s   s = V x t s = 90km/h x 6min = 90km/h x 0,1h = 9km s = 9km [droga po 6 minutach]
