Aman travels a distance of 12 km in the north direction and he turns to the east and travels a distance of 5 km. He further turns to the north and travels 3 km and then he turns in the east direction and travels a distance of 4 km. Finally he turns in the south direction and travels a distance of 15 Km. What is the shortest distance between his starting and end positions? {All turns are 90 degree turns only}

·        Aman travels a distance of 12 km in the north direction and he turns to the east and travels a distance of 5 km. He further turns to the north and travels 3 km and then he turns in the east direction and travels a distance of 4 km.

·        Finally he turns in the south direction and travels a distance of 15 Km.

Shortest distance between starting and end positions =5+4= 9 km

Thus, correct option is (b).
