The answer is 47.5.
The equation for this problem is:
60(H) + (M) divided by 2.
Plug the numbers of the time in the equation,
60(3) + (25) / 2
180 + 25 / 2 = 205/2
205/2 = 102.5 (Smaller Angle)
Then you calculate the angle between 12 and the Minute hand 25.
0m= 6M
0m = 6(25)
0m= 150
Final step is to subtract the hour angle by the minute angle.
H(102.5)-(150)= -47.5 or 47.5 degrees
Hope this helps,
