On a classroom clock, the large (minute) hand on the clock will travel through an angle of 120 degrees in some time. What angle does the small (hour) hand pass in this time?

Correct answer:

β =  10 °

Step-by-step explanation:

$$\begin{gathered} \alpha =120{}^{\circ } \\ A:360{}^{\circ } \\ B:360{}^{\circ } \\ \beta =\alpha /12=120/12=10^{\circ } \end{gathered}$$
