24 de grade 15 minute 23 de secunde+ 5 grade 48 minute

Answer 1

31 grade 15 minute 71 secunde si secundele le transformi in minute adica 60 secunde=1 min deci raman 31 grade 16 minute si 11 secunde
29 grade 63 minute si 23 secunde acum transformi minutele in grade adica 60 minute= 1 grad=> 30 grade 3 minute si 23 secunde
