Shyam walks 5 km towards east, then turns left and walks another 6 km. Then turns right and walks 9 km. Finally he turns right and walks 6 km. At what distance is he now from the starting point?
Explanation:
Shyam goes 5 km East, then 6 km North, then 9 km East, then 6 km South. The North and South movements cancel out. Total distance from the start = 5 km + 9 km = 14 km East.
Explanation:
Assume they sit around a table facing the centre. X faces west (sits east). X's left is south, so Y sits south facing north. Remaining positions: west and north. V is right of Z, so Z sits west (facing east) and V sits north (facing south). Hence V faces south.
