100km/h=.....m/s
45cm/min=....m/s
600m/min=....km/h
VA ROG MULT !!!!​

Answer 1

Răspuns:

stim ca 1 h = 60 min = 3600 s

             1 km = 1000 metri

18 m/s = 18 x 3600 : 1000 = 64,8 km/h

100 km/h = 100 000 m : 3600 s = 27,77 m/s

45 cm /min = 0,45 m : 60 s = 0,0075 m/s

600 m/min = 600 x 60 :1000 = 36 km/h
