In a clock, hour hand takes how many rounds of the clock face to compl...
Explanation:
To understand how many rounds the hour hand takes to complete a day, we need to analyze the movement of the hour hand and the concept of time on a clock.
Movement of the Hour Hand:
- The hour hand of a clock moves at a constant rate. It completes a full rotation around the clock face in 12 hours.
- In 12 hours, the hour hand moves from the 12 o'clock position to the 12 o'clock position again, completing one full round.
Time on a Clock:
- A day consists of 24 hours.
- The clock face is divided into 12 equal parts, representing the hours.
- As the hour hand moves, it indicates the current hour on the clock face.
Calculating the Number of Rounds:
- Since the hour hand completes one full round in 12 hours, we can calculate the number of rounds it will complete in 24 hours (a day).
- In 24 hours, the hour hand will move twice the distance it covers in 12 hours.
- Therefore, the hour hand will complete 2 rounds of the clock face in a day.
Conclusion:
The hour hand takes 2 rounds of the clock face to complete a day. Thus, option B - 2 rounds is the correct answer.
