You're on a roll — here is the completed table for Question 4: To complete the table, we use the following relationships: • The Earth rotates 360^ in 24 hours. • This means 1 hour corresponds to 15^ of longitude (360^ / 24 hours = 15^/hour). • Conversely, 1^ of longitude corresponds to 4 minutes (60 minutes / 15^ = 4 minutes/^). • Locations East of UTC are ahead in time, and locations West of UTC are behind in time. • UTC time is given as 12:00. Here are the calculations for each row: Rio de Janeiro: Longitude of Rio de Janeiro is approximately 43^. Difference in degrees: 43^. Difference in time: 43^ × 1 hour15^ = 2.866... hours = 2 hours and (0.866 × 60) minutes = 2 hours 52 minutes. Ahead/Behind: West of UTC, so Behind. Time: 12:00 - 2 hours 52 minutes = 09:08. Berlin: Longitude of Berlin is approximately 13^. Difference in degrees: 13^. Difference in time: 13^ × 1 hour15^ = 0.866... hours = 0 hours and (0.866 × 60) minutes = 0 hours 52 minutes. Ahead/Behind: East of UTC, so Ahead. Time: 12:00 + 0 hours 52 minutes = 12:52. Perth: Longitude of Perth is approximately 116^. Difference in degrees: 116^. Difference in time: 116^ × 1 hour15^ = 7.733... hours = 7 hours and (0.733 × 60) minutes = 7 hours 44 minutes. Ahead/Behind: East of UTC, so Ahead. Time: 12:00 + 7 hours 44 minutes = 19:44. Tehran (first entry): Given: Difference in time is 3.5 hours. Difference in degrees: 3.5 hours × 15^/hour = 52.5^. Ahead/Behind: Since the time is later than UTC (as indicated by the 3.5 hours ahead), it is Ahead. Time: 12:00 + 3 hours 30 minutes = 15:30. Tehran (second entry): Given: Ahead, Time is 15:30. Difference in time: 15:30 - 12:00 = 3 hours 30 minutes = 3.5 hours. Difference in degrees: 3.5 hours × 15^/hour = 52.5^. Ahead/Behind: Ahead (pre-filled). Here is the completed table: | COUNTRY | DIFFERENCE IN IN ^ | DIFFERENCE IN TIME | AHEAD/BEHIND OF THE UTC | TIME | | :-------------- | :----------------------------- | :----------------- | :---------------------- | :----- | | Rio de Janeiro | 43^ | 2.87 hrs (2h 52m) | Behind | 09:08 | | Berlin | 13^ | 0.87 hrs (0h 52m) | Ahead | 12:52 | | Perth | 116^ | 7.73 hrs (7h 44m) | Ahead | 19:44 | | Tehran | 52.5^ | 3.5 hrs | Ahead | 15:30 | | Tehran | 52.5^ | 3.5 hrs | Ahead | 15:30 | Send me the next one 📸
