Two cars A and B starts from the same point and move in opposite direction. A towards north by 6 km and B towards south by 6 km. Then A again travels towards east by 5 km. Which is the shortest path B can take to reach A?


A. 4
B. 10
C. 6
D. Can't be determined
E. 13
F. none of these

  A
  It forms a right angle triangle with two arms of length (6+6)=12 km and 5 km.
  The shortest path would be the hypotenuse. There fore the shortest path length would be (12*12 + 5*5)^(1/2) = (169)^(1/2) =13.

  Form a right angle triangle from A to B.
  6+6=12. and we have 5km.
  As per pythogora's theorem we have s2+s2=hyp2
  (12)^2+5^2=169 whose root is 13.
