Welche Aussagen sind wahr, welche falsch? Wähle die richtigen aus.
Für diese Aufgabe benötigst Du folgendes Grundwissen: Umrechnung von Zeiteinheiten
1.Aussage:
[(703.768 : 60) : 60] : 24 = 8,15d
(8 ⋅ 60 ⋅ 60 ⋅ 24) = 691.200s
703.768 - 691.200 = 12.568s
(12.568 : 60) : 60 = 3,49h
(3 ⋅ 60 ⋅ 60) = 10.800s
12.568 - 10.800 = 1.768s
(1.768 : 60) = 29,47min
(29 ⋅ 60) = 1.740s
1.768 - 1.740 = 28s
⇒ 703.768 = 8d 3h 29min 28s ⇒ 703.768 = 8d 3h 12min 44s
2.Aussage
[(589.492 : 60) : 60] : 24 = 6,82
(6 ⋅ 60 ⋅ 60 ⋅ 24) = 518.400
589.492 - 518.400 = 71.092s
(71.092 : 60) : 60 = 19,75h
(19 ⋅ 60 ⋅ 60) = 68.400s
71.092 - 68.400 = 2.692s
2.692 : 60 = 44,87min
44 ⋅ 60 = 2.640
2.692 - 2.640 = 52s
⇒ 589.492s = 6d 19h 44min 52s ⇒ richtig
3.Aussage
(17.729 : 24) : 365 = 2,02a
(2 ⋅ 24) ⋅ 365 = 17.520h
17.729 - 17.520 = 209h
(209 : 24) = 8,71d
(8 ⋅ 24) = 192h
209 - 192 = 17h
⇒ 17.729h = 2a 8d 17h ⇒ 17.729h = 2a 16d 23h
4.Aussage
(25.870 : 24) : 365 = 2,95a
(2 ⋅ 24 ⋅ 365) = 17.520
25.870 - 17.520 = 8.350h
8.350 : 24 = 347,92d
347 ⋅ 24 = 8.328h
8.350 - 8.328 = 22h
⇒ 25.870h = 2a 347d 22h ⇒ 25.870 = 2a 340d 22h
5.Aussage
(92.440 : 60) : 24 = 64,19d
(64 ⋅ 60) ⋅ 24 = 92.160min
92.440 - 92.160 = 280min
(280 : 60) = 4,67h
(4 60) = 240min
280 - 240 = 40min
⇒ 92.440min = 64d 4h 40min ⇒ richtig
