Consider the following statements:
- An aircraft takes off from Papeete (Tahiti, 150 W) at 4 p.m. on Monday and lands at Port Moresby (Papua New Guinea, 150 E) at 6 a.m. on Wednesday.
- The same aircraft makes a return from Port Moresby at 12 noon on Wednesday and lands at Papeete at 11 a.m. on the same day (Wednesday).
Which of the above statement(s) is/are correct?
Correct answer: C
Explanation
Papeete (150 W) is at UTC-10 and Port Moresby (150 E) is at UTC+10, a 20-hour gap. For statement 1, departing Papeete 4 p.m. Monday converts to 02:00 Tuesday UTC, and arriving Port Moresby 6 a.m. Wednesday is 20:00 Tuesday UTC, giving an 18-hour flight. For statement 2, departing Port Moresby noon Wednesday is 02:00 Wednesday UTC, and arriving Papeete 11 a.m. Wednesday is 21:00 Wednesday UTC, a 19-hour flight. Both are internally consistent.
