If i left Port Moresby at 1:25 pm local time and arrived at my destination at 6:00 pm local time,how long is my trip?

To calculate the duration of your trip, you need to subtract the departure time from the arrival time.

Departure time: 1:25 pm
Arrival time: 6:00 pm

To convert these times into a 24-hour format:
Departure time: 13:25
Arrival time: 18:00

Now, subtract the departure time from the arrival time:
18:00 - 13:25 = 4 hours and 35 minutes

Therefore, your trip duration is 4 hours and 35 minutes.
