Answer 1

2 h + 10 min = 120 min + 10 min = 130 min
5 s + 2 min = 5 s + 120 s = 125 s
120 s + 6 min = 2 min + 6 min = 8 min
150 s - 2 min = 150 s - 120 s = 30 s
30 min - 7 min = 1800 s - 420 s = 1380 s

3 h + 9 min = 180 min + 9 min = 189 min
180 min - 2 h = 180 min - 120 min = 60 min
8 h + 3 zile = 8 h + 72 h = 80 h
96 h + 6 zile = 4 zile + 6 zile = 10 zile
10h - 120 min = 10 h - 2 h = 8 h

3 h 5 min + 2 h 55 min = 5 h 60 min = 6 h
14 h 45 min - 3 h 45 min = 11 h 0 min = 11 h
6 h 25 min - 1 h 25 min = 5 h 0 min = 5 h
8 h 20 min + 3 h 40 min = 11 h 60 min = 12 h
6 h 25 min - 2 h 25 min = 4 h 0 min = 4h
