Answer: DThe hands of a clock are 35 min =(35*6 = 210 degree) apart at 7 o' clock.
For the hands to be together, the minutes hand has to gain 210 degree min over the hour hand.
Speed of the minute hand relative to the hours hand = 6- (1/2) = 5.5 degree per min.
Hence the hands will meet after 210 /5.5
