Explanation:

Given

Required

What time did Raj arrived Delhi

First, we'll calculate the time difference between Sydney and Delhi

Difference = 1 pm - 7:30 am

Convert time to 24 hour format

Difference = 13:00 - 7:30

Difference = 5 hours 30 minutes

Next is to convert his departure time in Sydney to Delhi Time equivalent

Time of departure = 10:00 am (Sydney)

Delhi Time = 10:00 am - 5 hours 30 minutes

Delhi Time = 4:30 am

Lastly, we can then calculate Raj arrival time;

Since the flight took him 13 hours;

Arrival Time = 4:30 am + 13 hours

Arrival Time = 5:30pm

reflecting point a across the origin negates both of its coordinates.
