Solve the following question:
Question: A student bikes to school by traveling first dN = 1.00miles north, then dW = 0.500miles west, and finally dS = 0.200miles south.
A- If a bird were to start out from the origin (where the student starts) and fly directly (in a straight line) to the school, what distance db would the bird cover?
I need help to find what distance db the bird would cover. Express your answer in miles. Thanks.
