Answer 2

1 grad are 60 de minute 60 minute= 60 secunde 
12grade x60 minute=720 de minute

10 gradex60minute =600 minute+5 minute=605minute

2 grade x 60 minute=120 minute   120 minute x 60 secunde=7200 secunde+4 secunde=7204 secunde

15 grade x 60minute= 900 minute+4 minute=904 minute x 60 secunde= 54240 secunde

180 grade x 60 minute=10800 minute +10 minute=10810 minute x 60secunde= 648600 secunde
