Question

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

Answer 1

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.

Answer 2

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]
