A girl went for her examination then she saw that the clock showed 9:00 a.m. after her exam she saw that the clock showed it was 12:30 p.m. How many degrees has the hour hand moved? Correct Answer <p>105° </p>

Here the time difference is 9:00 to 12.30 = 3.30 hours.

The clock makes a 30° angle when it completes 1 hour. so 3 h = 90°

Also, the clock makes a 15° angle when it completes 30 minutes.

So, the total angle = 90 + 15 = 105°

Hence, the correct answer is 105°.
