What time after 8 o’ clock will the hands of the continuously driven clock be opposite each other?
---------------------
At 8, the angle is 120 degrees
In t minutes, the minute hand will move 6t degrees
In t minutes, the hour hand will move t/2 degrees
-------------
Find t so that the angle is 180 degs
-----
Angle = 120 + 6t - t/2 = 180
11t/2 = 60
t = 120/11 minutes
Time = 8:10:54.5454...
