Did you check similar questions before entering this one? This kind of question comes frequently with different longitudes and times. I’m sure I’ve seen exactly this question before.
Take a look at and the time zone map at , and adapt the values:
Find a convenient time zone at 0°. From the map, time zones include UTC, UTC+1 and UTC+2. So your “12 noon” could correspond to 10:00, 11:00 or 12:00 UTC.
Find a convenient time zone at 75° E. From the map, time zones include UTC+4:30, UTC+5 and UTC+6. So the time there could be 14:30, 15:00, 16:30, 17:00 or 18:00.
Can you tell me why you asked this seemingly meaningless question? Do you have a teacher who has slept through the introduction of time zones 150 years ago?
EDIT: Ciro Pabon replied to my comment on his answer by asking:
How can I know, by heart, what local time should you use if, for example , the longitude is 139 degrees west?
You can't, of course. That's why you need to look up the location (and not just the longitude), for example on the map. He claims that you have to think in terms of solar time. I disagree.
He continues:
Besides, you have to walk a bit in the shoes of the OP: the question seems to come from a a school student that is learning how the Earth turns and how much is a degree.
Yes, I agree, it's a homework assignment. But the expected answer is JUST PLAIN WRONG. It gives the poor students the impression that solar time still has a meaning. It doesn't. All the more reason to be very pedantic.
