200 h = ... j ... h

200/24 ~ 8,33 j

200 - 24 x 8 = 200 - 192 = 8 h

200 h = 8 j 8 h

2 semaines = ... h

2 x 7 j x 24 h = 336 h

2 semaines = 336 h

503 h = ... j ... h

503/24 ~ 20,96 J

503 - 24 x 20 = 503 - 480 = 23 h

503 h = 20 j 23 h

800 min = ... h ... min

800/60 ~ 13,33 h

800 - 60 x 13 = 800 - 780 = 20 min

800 min = 13 h 20 min

1058 min = ... h .... min

1058/60 ~ 17,63 h

1058 - 60 x 17 = 1058 - 1020 = 38 min

1058 min = 17h 38 min

975 s = ... min ... s

975/60 = 16,25 min

975 - 60 x 16 = 15 s

975 s = 16 min 15 s

4000 s = ... min ... s

4000/60 ~ 66,67 min

4000 - 60 x 66 = 4000 - 3960 = 40 s

4000 s = 66 min 40 s

19000 s = ... min ... s

19000/60 ~ 316,67 min

19000 - 316 x 60 = 19000 - 18960 = 40 s

19000 s = 316 min 40 s

19000 s = ... h ... min ... s

316/60 ~ 5,27 h

316 - 5 x 60 = 316 - 300 = 16 min
