To calculate the angle between clock hands:
1. Minute hand moves at 6° per minute (360°/60 minutes)
2. Second hand moves at 6° per second (360°/60 seconds)
3. However, the question mentions 25 minutes apart, which likely refers to the minute markers (not seconds)
If they're 25 minutes apart on the clock face:
- Each minute represents 6°
- 25 minutes × 6° = 150°
The smaller angle between them would be 150° (as the larger angle would be 210°). Therefore, the correct answer is (1) 150°.
