A lady runs 18 kms towards east and then 24 kms towards north.How far is she from her starting point and in which direction?

• let her starting point is x
  than( x)2 = (18)2 + (24)2
  (x)2 = 900
  x=30 and direction will be north-east.

  Let the lady be at the position x initially. She walks 18 kms east and then 24 kms north. Now she is in the north-east direction at a distance of square root(18^2 +24^2) i.e 30 kms. (Pythagoras theorem)

• answer is 30 (i.e) it is similar to the diagnol of the triangle so sqare root of a*a+b*b so the diagnal is obtained square root of 900 so answer is 30

• She has done 42km and is in north.

• Based on pythagoras' theorem:
  Her runs make a right angle triangle as follows:-
  so (hypotense)^2=(base)^2 +(perpendicular)^2

• starting point distance =Sq root of(24^2 + 18^2)
  =30.
• 9 years agoHelpfull: Yes(0) No(0)
• 18^2+24^2=900, sqareroot of 900=30
