Question

180 dm/min=?m/s
36 m/min=?cm/s​

Answer 1

180 dm/min= 18m : 60min= 0,3m/s
36m/min= 3600cm : 60min= 60cm/s

Answer 2

Inlocuim valorile cu unitatile SI :

1 dm = 0,1 m => 180 dm = 180 x 0,1 = 18 m

36 m = 36 x 100 = 3600 cm

1min = 60 s  

si facem calculele necesare :

180 dm/min = 18 m : 60 s = 0,3 m/s

36 m /min = 3600 cm / 60 s = 60 cm/s
