Question

12,36 luni = ? sec. vă rog ​

Answer 1

$12 \ luni=1 \ an=365 \ zile \ (dac\u{a} \ nu \ e \ bisect); \\ \Rightarrow \ 1 \ lun\u{a}=\frac{365 \ zile}{12}=30,41(6) \ zile; \\ \Rightarrow 12,36 \ luni=30,41(6)\cdot 12,36=375,95 \ zile; \\ 1 \ zi=24 \ h \\ \Rightarrow \ 12,36 \ luni=375,95 \cdot 24 \ h=9 \ 022,8 \ h \\ 1 \ h=60 \ min \\ \Rightarrow 12,36 \ luni=9 \ 022,8\cdot 60 \ min=541 \ 368 \ min \\ 1 \ min=60 \ sec \\ \Rightarrow 12,36 \ luni=541 \ 368 \cdot 60 \ sec \\ \Rightarrow \boxed{12,36 \ luni=32 \ 482 \ 080 \ sec}$

Iar dacă e bisect mai adaugi 86 400 secunde.
