While walking on a plane surface, a traveler first headed 18 miles north, then 11 miles west, then 6 miles south and finally 6 miles east. How many miles from the starting point was the traveler after these four legs of the journey?

18-6=12

11-6=5

Then, we use the Pythagorean Theorem.

sqrt(12^2+5^2)

=sqrt(144+25)

=sqrt(169)

=13.

Hope this helped!

Here's  one way of doing this

Let the starting  point  = (0,0)

So  18 mi  north puts us at (0,18)

11 miles west of here puts us at  (-11,18)

6 miles south puts us at  ( -11, 12)

6 miles  east puts us at   (-5 , 12)

These are two legs  of  a 5, 12, 13  right triangle

So...we are  13  miles from our starting point
