If a plane leaves New York for London at 3:00 p.m. (local time) and the flight duration is of 7 hours, what time would the plane land, if London is 5 hours ahead of New York?

Given:

Departure times in New York for London (local time) → 3:00 p.m.

Flight duration → 7 hours

Time difference → 5 hours ahead of New York

So,

Arrival time in London from New York → 3:00 p.m. + 7 hours ⇒ 10:00 p.m. (New York time)

Time at which the plane would land:

According to the question considering the time difference → 10:00 p.m. + 5 hours ⇒ 3:00 a.m. (London time)

Hence, "Option 1" is the correct answer.
