60'=360 deg then
12 hrs=360 deg
12-60
6 - ? = (60*6)/12=180 deg
12 hrs=360 deg
12-60
6 - ? = (60*6)/12=180 deg

Angle = mod(5.5*2m - 30*h);
where m=minute, h=hour;
where m=minute, h=hour;

Clock is consider as circle 360 deg
the duration of Time= 6 hrs
total = 12 hrs
calculated deg=time duration*deg/total hrs
=6(360/12)=180
the duration of Time= 6 hrs
total = 12 hrs
calculated deg=time duration*deg/total hrs
=6(360/12)=180

HEY MARAN...HERE IS A ONE MORE METHOD 2 SOLVE DIS...
SEE WE HAVE TO FIND THE DEGREE @ 2p.m.
1 HR=30 DEGREES
SO THE GAP TIME BETWEEN 8a.m. to 2p.m. IS 6 HRS...
SO 6*30=180 DEGRESS...
I HOPE U UNDERSTOOD....

Each hour takes 180 degree to rotate.
That's very simple concept each clock takes a complete rotation to complete an hour. So one complete rotation denotes the angle of 180 degree.
