The famous Denali Star train starts from anchorge & travels towards fair banksat speed 50 mph.After some time another train Glacier Discovery Train( At parallel track) at fair banks And moves towards Anchorge at a speed of 70 mph. Both the trains Denali star & Glacier discovery have a length 1/6 miles each .After the trains meet how many seconds will faster train take to overtake the slower one?	Pick one
A) 10 sec
B) 11 sec
C) 12 sec
D) 13 sec
E) 14 sec
total distance = (1/6)+(1/6) = 1/3 miles   relative speed = (50+70)=
