**jai**, Monday, October 25, 2010 at 12:54amto find distance, use the distance formula:

d = sqrt[(y2-y1)^2 + (x2-x1)^2]

but first, we look for the points,, let the starting point at the origin (0,0) -- this is (x1,y1)

then it traveled 5 miles south (0,-5)

and finally, it traveled 11 miles east, thus (11,-5) -- this point is (x2,y2)

therefore,

d = sqrt[(-5-0)^2 + (11-0)^2]

d = sqrt(25 + 121)

d = sqrt(146) = 12.083

so there,, :)
