Check my work.
Calculate the correct time in brackets:
1. 1:00am at 30W = (11:00pm) at 60W
2. 3:00pm at 15W = (1:00pm) at 45W
3. 1:00pm at 120E = (9:00am) at 60E
4. 12:00pm at 15E = (6:00pm) at 105E
5. 11:00am at 15E = (9:00am) at 15W
Calculate the correct longitude in brackets:
6. 6:00pm at Prime Meridian = 10:00pm at (60E)
7. 2:00pm at 150W = 1:00pm at (165W)
8. 12:00pm at 45E = 8:00pm at (165E)
9. 10:00am at 30E = 4:00am at (60W)
10. 5:00pm at 165E = 10:00am at (60E)
Can someone please check to see if I'm doing it right? If not please correct me.
Appreciate your help.

To check your work, we need to understand how time zones and longitude work.
1. To convert time in different time zones, you need to know the time difference between the two longitudes. The time difference decreases by 1 hour for every 15 degrees of longitude you move to the east. Similarly, it increases by 1 hour for every 15 degrees of longitude you move to the west.
Let's check each question:
1. 30W to 60W: The time difference is 2 hours because you are moving east by 30 degrees. Since it's 1:00am at 30W, adding 2 hours gives 3:00am. So the correct answer is (3:00am), not 11:00pm.
2. 15W to 45W: The time difference is 3 hours because you are moving east by 30 degrees. Since it's 3:00pm at 15W, adding 3 hours gives 6:00pm. So the correct answer is (6:00pm), not 1:00pm.
3. 120E to 60E: The time difference is 4 hours because you are moving west by 60 degrees. Since it's 1:00pm at 120E, subtracting 4 hours gives 9:00am. So the correct answer is (9:00am), as you correctly calculated.
4. 15E to 105E: The time difference is 4 hours because you are moving east by 90 degrees. Since it's 12:00pm at 15E, adding 4 hours gives 4:00pm. So the correct answer is (4:00pm), not 6:00pm.
5. 15E to 15W: The time difference is 2 hours because you are moving west by 30 degrees. Since it's 11:00am at 15E, subtracting 2 hours gives 9:00am. So the correct answer is (9:00am), as you correctly calculated.
Now let's move on to the longitude calculations:
6. Prime Meridian to 60E: The time difference is 4 hours because you are moving east by 60 degrees. Since it's 6:00pm at the Prime Meridian, adding 4 hours gives 10:00pm. So the correct answer is (10:00pm), not 10:00pm at 60E.
7. 150W to 165W: The longitude difference is 15 degrees. Since it's 2:00pm at 150W, and moving west, subtracting 1 hour gives 1:00pm. So the correct answer is (1:00pm), as you correctly calculated.
8. 45E to 165E: The longitude difference is 120 degrees. Since it's 12:00pm at 45E, and moving east, adding 8 hours gives 8:00pm. So the correct answer is (8:00pm), as you correctly calculated.
9. 30E to 60W: The longitude difference is 90 degrees. Since it's 10:00am at 30E, and moving west, subtracting 6 hours gives 4:00am. So the correct answer is (4:00am), as you correctly calculated.
10. 165E to 60E: The longitude difference is 105 degrees. Since it's 5:00pm at 165E, and moving west, subtracting 7 hours gives 10:00am. So the correct answer is (10:00am), as you correctly calculated.
In summary, questions 1, 2, and 4 have incorrect answers, while the rest are correct.
