Question

the hand of the clock below is pointing at the 7. suppose that the hand moves clockwise until it points at the 12. how many degrees does the hand move?

Explanation:

Step1: Calculate degrees per clock mark

A full clock circle is $360^\circ$, divided into 12 equal marks.
$\text{Degrees per mark} = \frac{360^\circ}{12} = 30^\circ$

Step2: Count clockwise intervals from 7 to 12

Moving clockwise from 7 to 12 covers 5 intervals (7→8, 8→9, 9→10, 10→11, 11→12).

Step3: Total degrees moved

Multiply intervals by degrees per mark.
$\text{Total degrees} = 5 \times 30^\circ = 150^\circ$

Answer:

$150$
