The minute hand rotates 360 degrees in 60 minutes, so in 15 minutes it would have rotated:
360 degrees / 60 minutes * 15 minutes = 90 degrees
Since the hour hand is stuck at the 3 o'clock position, the minute hand must have rotated an additional 90 degrees to reach the angle of -105 degrees with the hour hand.
Therefore, the minute hand could have rotated a total of 90 degrees to reach its current position.
Neela's clock is broken. The minute hand rotates around the clock correctly, but the hour hand is stuck in the three o'clock position. Suppose Neela first looks at the clock when the hands are aligned and it shows 3:15She looks at the clock again and sees that the hour and minute hands of the clock form the arms of an angle measuring -105How many degrees could the minute hand have rotated to reach its current position ?
