Clockhand, 12hr 1 rpm: 360÷ 12÷60=0.5 degrees.

At 12, the angle between the two pointers is 0 degrees.

When the two needles are on the same straight line again, the two needles form an angle of180.

That is to say, the minute hand turns more than the hour hand 180.

Time:180 ÷ (6-0.5) = 360/11min.

That is, after 360/ 1 1 min, the two needles are in the same straight line again.

At this moment,

Clockwise pointer rotation: 360/11× 0.5 =180/1degree.

Minute hand rotation: 360/11× 6 = 2160/1degree.
