The hour hand  will  move at  a rate  of 

360°  in 12 hrs

30° in  1 hr

30°/ 60  =  .5° in one minute

So  at   5:44.....the hour  hand has  moved   5 (30°) +  44(.5°)  =  [150 + 22]° = 172°   from 12 noon

The minute hand  will move  at a rate of 360°/ 60  = 6° per minute

So at 5:44...it will have moved  [44 * 6]°  = 264°  from the top of the hour

So...the smaller angle formed by the hands  =  [264 - 172]°  =  92°

You can also use this formula. \(|30h-5.5m|\), where \(h\) denotes the number of hours and \(m\) is the number of minutes. Thus, the answer is \(|150-242|=|-92|=92\) degrees.

What is the number of degrees in the smaller angle formed by the hour and minute hands of a clock at 5:44?

\(\text{Let the angle formed by the minute hand and hour hand in degrees $\mathbf{ \Delta \alpha }$ } \\ \text{Let the time in hours $\mathbf{ t }$ }\)

The formula between the two values \(\Delta \alpha\) and \(t\) is:
\(\boxed{~ \Delta \alpha = 330 \cdot t } \)

\(\begin{array}{|rcll|} \hline \Delta \alpha &=& 330 \cdot t \quad | \quad t= 5:44 = 5+\dfrac{44}{60}= 5.7\overline{3}\ h \\ &=& 330 \cdot 5.7\overline{3} \\ &=& 1892 \\ &=& 1892 -5\cdot 360 \\ &=& 1892 - 1800 \\ \mathbf{\Delta \alpha} &=& \mathbf{ 92^\circ } \\ \hline \end{array}\)
