C)
południk 0* - 12.00
Cardiff 3*W
Amsterdam 4*E
Paryż 2*E

Amsterdam 4* razy 4min = 16min 12.16
Paryż 2* razy 4min = 8min 12.08
Cardiff 3* razy 4min = 12min 12.12

10.
Cardiff 3*W 12.00

Paryż 3*W + 2*E = 6* 6* razy 4min = 24min 11.36
Londyn 3* razy 4min = 12min 11.48
Amsterdam 3*W + 4*E = 7* 7* razy 4min = 32min 11.28

11.
Londyn 0* - 12.00
Wrocław 17*E - ?

17* razy 4min = 68min = 1h 8min
12.00 + 1h 8min = 13.08 - Wrocław


12.
a)
NY 74*W - 12.00
Wrocław 17*E - ?

74*W + 17*E = 91*
91* razy 4min = 364min = 6h 4min
12.00 + 6h 4min = 18.04 - Wrocław

b)
NY 74*W - ?
Wrocław 17*E - 12.00

74*W + 17*E = 91*
91* razy 4min = 364min = 6h 4min
12.00 - 6h 4min = 5.56 - NY
