let same linein after x minutes.
minute hand:
for 60 min it cover angle 360
....1....................360/60
...x....................6x
hour hand:
for 60 min it cover angle 30
....1...................30/60
....x....................0.5x

now obviously the hour hand are place between 8 and 9
so,the min hand cover angle 12 hrs to 8hrs+0.5x
means,240+0.5x=6x
x=43.63 min

min hand should be in b/w 8 and 10
so take minimum number i.e 8
then 8*5=40
so min=40+40/11
=44.63 min
therefor time=43.63min
