A student bikes to school by traveling first dN = 1.00milesnorth, then dW = 0.500miles west, and finally dS = 0.200milessouth.
If a bird were to start out from the origin (where the studentstarts) and fly directly (in a straight line) to the school, whatdistance db would the bird cover?
Express your answer in miles.

You will now find the same quantity algebraically, without theneed to use much geometry. Take the north direction as the positivey direction and east as positive x. The origin isstill where the student starts biking.
Let d? N be the displacement vectorcorresponding to the first leg of the student's trip. Expressd? N in component form.
Express your answer as two numbers separated by a comma (e.g.,1.0,2.0). By convention, the x component is writtenfirst.
