Question

How many degrees does the hour hand on the clock turn when it moves from 12:00 noon to 6:00 pm?

Answer 1

The hour hand moves 180 degrees

Step-by-step explanation:

A full lap around the clock is 360 degrees since it makes a circle. Moving from 12-6 is exactly half a lap, making the degree change 180.

Answer 2

180°

Step-by-step explanation:

You want to know the number of degrees the hour hand of a clock moves from noon to 6 pm.

Hour hand

At noon, the hour hand points straight up, toward the 12 on the clock face.

At 6 pm, the hour hand points straight down, toward the 6 on the clock face.

The angle between straight up and straight down is a "straight angle". The measure of such an angle is 180°.

The hour hand moves 180° from noon to 6 pm.

Additional comment

The 12 numbers on the clock face are separated by angles of 360°/12 = 30°. The angle traveled in 6 hours by the hour hand is 6·30° = 180°.
