Vineet cycles 8 km south, then turns west and cycles 9 km, then turns north and cycles 6 km, then turns east and cycles 5 km, then turns to his left. Turns and cycles 2 km. Where is he now with respect to his starting position?
Explanation:
South 8 km, West 9 km, North 6 km, East 5 km, Left (North) 2 km. Total North-South: 8 South and (6 + 2) North = 0. Total East-West: 9 West and 5 East = 4 km West.
Radha walks 7 km towards south-east then she walks 14 km towards west from here she walks 7 km towards north-west and finally walks 4 km towards east. At what distance is he from the starting point?
