Q1. When the minute hand covers a duration of 1 hour 25 minutes, what angular distance does it cover?
Explanation
The minute hand completes one full circle, or 360°, in 60 minutes. Therefore, it moves 6° in one minute. A duration of 1 hour 25 minutes is 85 minutes, so the angular distance covered is 85 × 6° = 510°. The value 375° would correspond to 62.5 minutes, not 85 minutes. The value 480° represents 80 minutes of movement. The value 450° represents 75 minutes of movement. Hence, 510° matches the given duration exactly.
