12 hour covers 360 degrees.
Then 360/12 = 30 degrees.
That is one hour.
Then 360/12 = 30 degrees.
That is one hour.

Can we do like this;
(20/60)*30 = 10?
(20/60)*30 = 10?

By common sense it is clear that in 20 minutes the minute hand will move 20*6=120degree and the hour hand will move20*(1/2)=10degree.
Clearly min hand will be at 20 and hour hand will be 10degree apart.
Clearly min hand will be at 20 and hour hand will be 10degree apart.

This formula does not provide solution for all problems.
Ex. 11:43.
= 60*11 - 11*43/2.
= 187/2 = 93.5.
Which is not appropriate angle.

= 60*11 - 11*43/2.
