Answer 1

A - 27 grade 32 min + 15 grade 47 min - 32 grade 24 min = 12 grade si 55 min 
B - 145 grade 17 min 24 sec + 17 grade 24 min 15 sec + 4 grade 3 min si 57 sec = 166 grade 45 min 36 sec 
C - 45 grade - 24 grade 5 min 17 sec + 24 grade 55 min 12 sec = 46 grade 49 min 55 sec 
D - 180 grade - 72 grade 41 min 14 sec+ 19 grade  17 min 53 sec = 126 grade 36 min 39 sec
