b) 16h=?min
c)4200sec=?h
d)3h7200sec=?min​

Answer 1

Răspuns:

Explicație pas cu pas:

1 h = 60 min

a) 180 min = 180 : 60 = 3 ore

3 h 180 min = 3 h + 3 h = 6 h

b) 16 h = 16 x 60 = 960 min

c)

1 h = 3600 s

4200 s = 4200 : 3600 = 1,1(6) h

4200 s = 3600 s + 600 s = 1 h 10 min

d)

3 h = 3 x 60 = 180 min

1 min = 60 sec

7200 sec = 7200 : 60 = 120 min

3 h 7200 sec = 180 min + 120 min = 300 min
