1. Aduni gradele cu gradele, minutele cu minutele si secundele cu secundele :
30 + 29 = 59 grade
45' + 37' = 82'
25" + 45" = 70"
2. Transformi secundele in minute, minutele in grade :
70" = 60" + 10" = 1' si 10"
82' + 1' = 83'
8' = 60' + 23' = 1 grad si 23'
59 grade + 1 grad = 60 grade
Raspuns final : 60 grade 23' 10"
