Two horse drawn wagons start from the same farm. Wagon X travels South 4.5 km and then turns right and travels 7.5 km. In the mean while wagon Y travels 9 km North, then 3.5 km West, then 2 km North , then it turns left and travels 4 km. Where is wagon Y with respect to wagon X?

Let the two horse drawn wagons start from the same farm S. Wagon X (red) travels South 4.5 km to W and then turns right and travels 7.5 km towards west. In the mean while wagon Y (black) travels 9 km North, then 3.5 km West to reach U, then 2 km North , finally it turns left and travels 4 km westwards to stop at point Y.

=> XY = $$4.5+9+2=15.5$$ km

$$\therefore$$ Wagon Y is 15.5 km north with respect to wagon X.
