Solution (By JKExamLibrary)

Richa drives 8 km south, turns left and drives 4 km. She then turns left and drives for 11km. At what distance is he from the departure point, if there is a direct route between the two points?
Explanation:
Drives 8 km South, turns left (East) 4 km, turns left (North) 11 km. Net vertical = 11 - 8 = 3 km North. Net horizontal = 4 km East. Distance = √(3² + 4²) = 5 km.
