A man walked a certain distance south and then the same distance plus 7km due west.He is now 13km from his starting point.What are the distances south and west that he walked? Choose the correct choice from the following options:
A) 5,12 B) 6,12 C) 7,12 D) 5,13 E) 6,13
If a man walked distance(in km) 'x' towards south &amp; then 'x+7'towards west.   Distance from starting point=Hypotenuse of a right triangle with sides x &amp; (x+7)   So 13^2=x^2+(x+7)^2   x^2+7x-60=0 or (x+12)(x-5)=0, so x=5   Distance towards west=x+7=5+7=
