the two clks have 1hr difference in 30hrs...1st clock runs 1 min faster and 2nd runs slower so when clock one shows 12.01, clock shows 11.59 and in the next upcoming hrs it will be 1.02 & 12.58,2.03 & 1.57 and so .It is seen tat difference is 2,4,6,...minutes so in 30hrs we get difference of 1 hour

In 1 hour there is a time difference of 1+1 min/hr.
i.e 2 min difference is there in 60 min
so, 1 min difference will be there in 60/2 min

therefore, 60 min or 1 hour difference will be there in (60/2)*60=1800 min
= 30 hours
