A student bikes to school by traveling first dN $=1\mathrm{.}10$ miles north, then dW $=0\mathrm{.}400$ miles west, and finally dS $=0\mathrm{.}200$ miles south.Take the north direction as the positive y direction and east as positive x$.$ The origin is still where the student starts biking. Let d$$N be the displacement vector corresponding to the first leg of the student's trip. Express d$$N in component form.

Express your answer as two numbers separated by a comma $($e$.$g$.,1\mathrm{.}0,2\mathrm{.}0).$ By convention, the x component is written first.
