A student bikes to school by traveling first dN = 0.800 miles north, then dW = 0.300 miles west, and finally dS = 0.200 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 d⃗N be the displacement vector corresponding to the first leg of the student's trip. Express d⃗N 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 written first.
