It is noon in Addis Ababa at 39°E. What is the time in Dar es Salaam on the same longitude?

1. Local time is determined by longitude, since the Earth turns through 15° of longitude every hour. 2. Places sharing the same meridian therefore share the same local time. 3. Addis Ababa and Dar es Salaam both lie on 39°E. 4. So when it is noon in one, it is noon in the other. 5. A time difference would require a difference in longitude, and here there is none. _Source: NECTA CSEE 2023 Geography 013, Question 1: Multiple Choice Questions, item (vii)_
