Angle between hour hand and minute hand = 30*H - 11/2*M
When the hour hand and minute hand are in straight line, angle = 180degree

30*H - 11/2*M = 180

Between 8:00 hrs and 9:00 hrs H = 8

11/2*M = 240 - 180 = 60
M = 120/11

time = 8 hours 120/11 minutes
8:120/11

two hands are in st.line at x hr:5x+5x/11+32+8/11 mins
let x=7 then 7 : 35+35/11+32+8/11
7 : 67+3+2/11+8/11
7 : 70+10/11
8 : 10+10/11
Ans: 8 hrs 10 mins 10/11 secs

hands are same line angle=180dgre
12hrs(h-h) =360degree ,1hr(60min)(m-h)=360
1hr(h-h)=30degre ,1min(m-h)=6,m-h in relative to h-h is 6-0.5=5.5 or 11/2
8hrs=8*30=240degre

so that(h-h)angle is more

therefore angle between two hands(h-h&m-h)=240-(m-h)*5.5=180

=>(m-h)=10m 10/11sec
so total time is 8hr 10m 10/11sec
