Explicație pas cu pas:
5 min = 5*60 = 300 s
30 min = 30*60 = 1800 s
1/4 min = 60 : 4 = 15 s
3/2 min = 60*3/2 = 90 s
1 h = 3600 s
____________
1/2 h = 60/2 = 30 min
1/3 h = 60/3 = 20 min
1/12 h = 60/12 = 5 min
5/6 h = 60*5/6 = 50 min
3/20 h = 60*3/20 = 9 min
_______________
3600 min = 3600 : 60 = 60 h
483840 min = 483840 : 60 = 8064 h
5 zile = 5*24 = 120 h
1 saptamana = 7 zile = 7*24 = 168 h
