A woman goes out running. She first travels 5.2km north. She then turns and travels 3.6km west. Finally, she turns If a bird were to start out from the origin (where the woman starts) and fly directly (in a straight line) to her final location, what distance d would the bird cover?again and travels 2.6km south. We are assuming a flat rectangular world.

Answer 1

as usual, draw a diagram. We want the diagonal of a right triangle with legs 3.6 and 5.2

so, the distance is √(3.6^2+(5.2-2.6)^2) = 4.4
