Answer 2

Explicație:

a. 5h+4h+19h+6h= 34h

32 min + 58 min + 36 min +36 min = 162 min = 2h 42 min

18 sec + 50 sec +5 sec + 17 sec = 90 sec = 1 min 30 sec

34 h + 2 h + 42 min + 1 min + 30 sec = 36 h + 43 min + 30 sec

b. 32 min - 21 min 48 sec = 31 min 60 sec - 21 min 48 sec = 10 min 12 sec

c. 19 h 36 min 5 sec - 6 h 36 min 17 s =

19 h 35 min 65 sec - 6 h 36 min 17 sec = 18 h 95 min 65 sec - 6 h 36 min 17 sec = 12 h 59 min 48 sec
