Question

A glider lands 18 miles west and 5 miles south from where it took off. The result of the trip can be described by the vector (–18, –5). Use distance (for magnitude) and direction to describe this vector a second way.

Answer 1

Do you know how to normalize a vector and how to get the distance of a vector?

Answer 2

If you find the distance, you can use that and the unit vector to do exactly what they are saying.
