Option 1: 7:30 AM

This option is incorrect. If London broadcasts news at 10:30 AM, it would not be heard in Baghdad at an earlier time. Baghdad is located at a longitude of 45° E, which is ahead of London`s longitude of 0°. This means that the time in Baghdad will be later than the time in London.

Option 2: 9:00 AM

This option is incorrect. Similar to option 1, the time in Baghdad would be later than the time in London. Additionally, a two and a half hour delay from the original broadcast time is too short for the time difference between London and Baghdad.

Option 3: 1:30 PM

This option is correct. Since Baghdad is located 45 degrees east of London, there is a significant time difference between the two cities. Each degree of longitude accounts for approximately 4 minutes of time difference. Therefore, 45 degrees of longitude would correspond to a time difference of 180 minutes or 3 hours. Adding this to the original broadcast time of 10:30 AM in London, the news would be heard in Baghdad at 1:30 PM.

Option 4: 12:00 Noon

This option is incorrect.
