Let the time when he started be 6 hours x mins and the time when he ended be 8 hours y mins.
Starting time: HR HAND covers an angle of 30(6 + x/60), MIN HAND covers an angle of 6x
End time: HR HAND covers an angle of 30(8 + y/60), MIN HAND covers 6y
Equating them we get,
30(6 + x/60) = 6y and 30(8 + y/60) = 6x
Solving, we will get the value of y close to 33.56 mins
