What is the angle between the hands of a clock at 1:30?
Answer:
135°
Using the standard formula Angle = |30H - 5.5M|. Substituting H=1 and M=30 gives |30(1) - 5.5(30)| = |30 - 165| = |-135| = 135°.
1992
What is the angle between the hands of a clock at exactly 12:00?
Answer:
0°
At exactly 12:00, both the hour and minute hands perfectly overlap, pointing at the 12. Therefore, the angle between them is exactly 0°.
1993
What is the angle between the hands of a clock at exactly 11:00?
Answer:
30°
At 11:00, the hour hand points to 11 and the minute hand to 12, separating them by exactly 1 hour marking. 1 × 30° = 30°.
1994
What is the angle between the hands of a clock at exactly 10:00?
Answer:
60°
At 10:00, the shortest distance between the hands spans 2 hour markings (from 10 to 12). 2 × 30° = 60°.
1995
What is the angle between the hands of a clock at exactly 9:00?
Answer:
90°
At 9:00, the hour hand is at 9 and the minute hand is at 12. The shortest distance between them spans 3 hour markings. 3 × 30° = 90°.
1996
What is the angle between the hands of a clock at exactly 8:00?
Answer:
120°
At 8:00, the hands are separated by 4 hour markings on the shorter side of the clock face (from 8 to 12). 4 × 30° = 120°.
1997
What is the reflex angle between the hands of a clock at exactly 7:00?
Answer:
210°
At 7:00, the smaller (interior) angle is 5 × 30° = 150°. The reflex angle is the larger angle measuring more than 180°. Therefore, the reflex angle is 360° - 150° = 210°.
1998
What is the angle between the hands of a clock at exactly 6:00?
Answer:
180°
At 6:00, the hour hand points to 6 and the minute hand points to 12. They form a perfect straight line, which measures 6 × 30° = 180°.
1999
What is the angle between the hands of a clock at exactly 5:00?
Answer:
150°
At 5:00, the hands are exactly 5 hour units apart. Multiplying the number of units by the degrees per unit gives 5 × 30° = 150°.
2000
What is the angle between the hands of a clock at exactly 4:00?
Answer:
120°
At 4:00, the hands are separated by 4 hour markings. Since each marking corresponds to 30°, the angle between them is 4 × 30° = 120°.
