Subtracting the given time from 11:60 yields 11:60 - 6:30 = 5:30.
92
What is the mirror image of a clock showing 5:55?
Answer:
6:05
Using the 11:60 subtraction rule: 11:60 - 5:55 = 6:05.
93
What is the mirror image of a clock showing 4:10?
Answer:
7:50
Subtract the given time from 11:60: 11:60 - 4:10 = 7:50.
94
What is the mirror image of a clock showing 3:45?
Answer:
8:15
Subtract the given time from 11:60 to find the mirror image: 11:60 - 3:45 = 8:15.
95
What is the mirror image of a clock showing 2:25?
Answer:
9:35
To find the mirror image, subtract the given time from 11:60. So, 11:60 - 2:25 = 9:35.
96
What is the angle between the hands of a clock at 12:40?
Answer:
140°
For 12:40, use H=0 and M=40. |30(0) - 5.5(40)| = |-220| = 220°. The interior angle is 360° - 220° = 140°.
97
What is the angle between the hands of a clock at 11:40?
Answer:
110°
Using |30(11) - 5.5(40)| = |330 - 220| = |110| = 110°.
98
What is the angle between the hands of a clock at 10:40?
Answer:
80°
Substitute H=10 and M=40: |30(10) - 5.5(40)| = |300 - 220| = |80| = 80°.
99
What is the angle between the hands of a clock at 9:40?
Answer:
50°
Using |30(9) - 5.5(40)| = |270 - 220| = |50| = 50°.
100
What is the angle between the hands of a clock at 8:40?
Answer:
20°
Substitute H=8 and M=40: |30(8) - 5.5(40)| = |240 - 220| = |20| = 20°.
