Answer: Sunday at 12h.
Explanation: The timezones are determined by the meridians, i.e., the longitudinal lines that crosses the Earth from pole to pole.
The initial referential is at GMT, abbreviation for <u>Greenwich</u> <u>Mean</u> <u>Time</u>, located at the Royal Observatory in the United Kingdom.
The Earth rotates 360° in 24 hours, so each 15° is exposed to the Sun for 1 hour. So, at each 15° we add an hour if the location is due to east or subtract an hour if the location is due to west.
Addis Ababa is located at 40°, which is in the band between 30° and 45°.
Counting from the referential, there are 3 timezones going east. So, we add 3 hours to the initial hour:
9h + 3h = 12h
And the day is the same since the difference is only 3 hours ahead.
Thus, fans located at 40° east will watch a football match on Sunday at 12h.
