Question: This evening in the nighttime sky over Texas, Mars can be seen until 12:10 AM. Jupiter does not appear until 2 hours and 41 minutes later, and Uranus does not appear until 3 hours and 16 minutes after Jupiter makes its first appearance.  How many minutes after 6:00 AM does Uranus first appear in the evening sky over Texas this evening?
Solution:
Jupiter appears 2 hours and 41 minutes after 12:10 AM, which can be calculated in two parts;
2 hours after 12:10 AM is 12:10+2:00 = 2:10 AM.
And an additional 41 minutes after 2:10 AM is 2:10+0:41 = 2:51 AM.
Uranus appears 3 hours and 16 minutes after 2:51 AM, which can be calculated in two parts:
3 hours after 2:51 AM is 2:51+3:00 = 5:51 AM.
And 16 minutes after 5:51 AM is 5:51+0:16 = 5:67 AM = 6:07 AM.
Thus, 6:07 AM is 7 minutes after 6:00 AM.
