Mogadishu and Kinshasa are on longitudes 45°E and 15°E respectively. If it is 11 30 hours in Mogadishu, what time is it in Kinshasa?
- A. 13 30 hours
- B. 09 30 hours
- C. 10 30 hours
- D. 07 30 hours
Verified working — step 1
Longitude gap = 45° − 15° = 30°, so time gap = 30 ÷ 15 = 2 hours. Kinshasa is west, so it is behind: 11 30 − 2 00 = …The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
