AJUTOR PLS.
Un ceas ramane in urma cu 105 secunde in 9 ore.Sa se calculeze cu cate minute si secunde va ramane in urma intr-o saptamana. dar intr un an bisect?

Answer 1

1 zi = 12 H => O SAPT = 7 ZILE => O SAPT = 7*12 = 84 H

Regula e 3 simpla : 
105s ..........................9H
 X s............................84H
X=105*84/9=> X=980 S

Raspuns : 980 secunde!

UN AN NEBISECT = 365 ZILE => 1 AN BISET = 365+1 = 366 ZILE

1 ZI = 12 H=> 366 ZILE = 366*12 = 4392 H

105s ..........................9H
 X s............................4392H

X=105* 4392/9 = 51240 SECUNDE
