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

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°

Ibelieve that c. recording would work best.
