What is the water image of a clock showing 4:40?
Answer:
1:50
Since the minutes (40) are greater than 30, subtract from 17:90 instead of 18:30. 17:90 - 4:40 = 13:50, which translates to 1:50.
82
What is the water image of a clock showing 3:30?
Answer:
3:00
Using the 18:30 rule: 18:30 - 3:30 = 15:00, which is identically 3:00.
83
What is the water image of a clock showing 2:20?
Answer:
4:10
Subtract the given time from 18:30: 18:30 - 2:20 = 16:10, which corresponds to 4:10.
84
What is the water image of a clock showing 1:15?
Answer:
5:15
To find the water image, subtract the given time from 18:30. 18:30 - 1:15 = 17:15, which translates to 5:15 in a 12-hour format.
85
What is the mirror image of a clock showing 12:25?
Answer:
11:35
For times past 12, subtract from 23:60. 23:60 - 12:25 = 11:35.
86
What is the mirror image of a clock showing 11:40?
Answer:
12:20
Since the hour is 11 or 12, we subtract from 23:60 instead of 11:60. So, 23:60 - 11:40 = 12:20.
87
What is the mirror image of a clock showing 10:50?
Answer:
1:10
Subtracting from 11:60 yields 11:60 - 10:50 = 1:10.
88
What is the mirror image of a clock showing 9:15?
Answer:
2:45

89
What is the mirror image of a clock showing 8:20?
Answer:
3:40
