Complete Question

A student bikes to school by traveling first dN = 0.900 miles north, then dW = 0.300 miles west, and finally dS = 0.100 miles south.

Similarly, let d⃗ W be the displacement vector corresponding to the second leg of the student's trip. Express d⃗ W in component form.

Express your answer as two numbers separated by a comma. Be careful with your signs.

The value is  

Explanation:

From the question we are told that

   The first displacement is   i.e positive  y-axis

   The  second displacement is   i.e negative  x-axis

   The final displacement is   i.e  negative  y-axis

Generally dW in component for is  

Generally the  total displacement of the student is mathematically represented as
