If a hardware timer is set to trigger an interrupt at exactly 3:15 PM, what is the interior angle between the hour and minute hands of an analog clock at that moment?
At 3:15, the minute hand is exactly on the 3. However, the hour hand has moved 1/4 of the way between 3 and 4. Since the gap between each hour is 30° (360/12), the hour hand has moved 30 times (15/60) = 7.5° away from the 3.
