Clock And Calendar

To find the angle between the minute and hour hand at 8:30, we follow these steps: - At 8:00, the hour hand is at the 8th position. The minute hand is at the 12th position. - The angle between each hour on the clock is . - So, at 8:00, the hour hand is at from the 12 o'clock position. - At 8:30, the minute hand is at the 6th position (30 minutes), which is from the 12 o'clock position. - The angle between the hour and minute hands is the difference between their positions: . Therefore, the angle between the two hands is . Thus, the correct answer is (B) 105°.

At 3:00, minute hand at 12 and hour hand at 3.
