What is the number of degrees in the acute angle formed by the hands of a clock at 6:44?

From the 12:00 position the hour hand moves   1/2 degree per minute

   the minute hand moves  6 degrees per minute

 

at 6 oclock + 44 minutes  the hour hand is at 180 degrees + 44 (1/2) = 202 degrees

   the minute hand at :44 is at     44 * 6 = 264 degrees

 

 

264 - 202 = 62 degrees between them

But at 6:44 the hour hand is not at 6 so this not an exact answer.

What is the number of degrees

in the acute angle formed by the hands of a clock at 6:44?

Formula: \(\boxed{\Delta\alpha^\circ = 330 * t^h}\)

 

\(\begin{array}{|rcll|} \hline \Delta\alpha^\circ &=& 330 * t^h \\\\ \Delta\alpha^\circ &=& 330 * (6+\dfrac{44}{60}) \\\\ \Delta\alpha^\circ &=& 330 * 6.7333333333^h \\ \Delta\alpha^\circ &=& 2222^\circ \\ \Delta\alpha^\circ &=& 62^\circ +6*360^\circ \\ \mathbf{\Delta\alpha^\circ} &=& \mathbf{62^\circ} \\ \hline \end{array}\)
