Los Angeles time is 18 hours behind Sydney time.If the timetable contains local times only, how long does the flight QF11 from Sydney to Los Angeles take?

To answer this question, we need more specific information such as the departure time from Sydney and the arrival time in Los Angeles. However, if we assume that the flight departs Sydney at a certain time and arrives in Los Angeles the same day, we can calculate the flight duration as follows:

1. Add 18 hours to the Sydney departure time to convert it to Los Angeles time.
2. Subtract the converted Sydney departure time from the Los Angeles arrival time.

For example, if the flight departs Sydney at 10:00 AM and arrives in Los Angeles at 6:00 AM the same day, the flight duration would be:

1. 10:00 AM Sydney time + 18 hours = 4:00 AM next day in Los Angeles time
2. 6:00 AM Los Angeles time - 4:00 AM Los Angeles time = 2 hours

However, since the flight actually arrived the previous day (due to the time difference), we need to add 24 hours to the flight duration. So, the total flight duration would be 24 hours + 2 hours = 26 hours.

Please note that this is a hypothetical example and the actual flight duration may vary.
