El día 14 de marzo de 2026, a hora civil del lugar Hcl=14h 06m 52s, en situación estimada l=35º30’N y L=011º30’W, se calcula la hora civil en Greenwich (HcG) en ese instante.On 14 March 2026 at local civil time HcL = 14h 06m 52s, at DR position l = 35º 30’ N, L = 011º 30’ W, calculate the Greenwich civil time (HcG) at that instant.
Show the answer
Correct answer: b) 14h 52m 52s
Why it is correct
Longitude 011º 30′ W equals 46 minutes of time (11º × 4m = 44m; 30′ × 4s = 2m). Being west of Greenwich, add them: 14h 06m 52s + 00h 46m 00s = 14h 52m 52s.
Why the others are not
- a) Subtracts 42 minutes instead of adding the 46 minutes for west longitude.
- c) Alters the seconds when converting the 30′ of arc.
- d) Subtracts longitude in time instead of adding it.
How to work it out in the exam
- 11º 30′ / 15 = 46m exact; in west longitude, HcG = HcL + L.
