How many degrees does the hour hand turn to get from 12:00 12:20?

120 degrees because 360degrees/60mins=6degrees per minute. 6x20mins=120 degrees

A clock has a circular shape therefore there's 360° central angle. The clock is divided into 12 equal parts because there are 12 hours.

=360°/12

=30°

Therefore, as the clock hour hand moves from 1 to 2 they moved 30°

= 30° (2 - 1)

= 30°

12:00 to 12:20

at 12:00 the clock hour hand is in 12

at 12:20 the clock hour hand is still in 12 but the minute hand is now located at 20/5 or 4.

Because the hour hand did not moved therefore the angle is 0°
