Time is now 11: 45 am what is the smaller angle between hour and minute hand on o'clock

Given that the time now is 11:45 a.m, the smallest and between the hour and minute hand on the o'clock will be given by:
 60 min=360 degrees
the time between the min hand and the hour hand is 10 min;
thus the angle will be:
10/60*360
=60 degrees

The expression of this would be 3.75x+y= 23
