A boy goes 10 km in the north direction from his school. From there he turns left and goes 15 km, and again turns left and goes 10 km. How far is the boy from his school and in which direction from the school?
A10 km and in North direction
B15 km and in South direction
C10 km and in West direction
D15 km and in West direction ✓ Correct
Correct answer: (D) 15 km and in West direction
Explanation
The boy is 15 km from school, to the West.
He goes 10 km north, then left (west) 15 km, then left (south) 10 km.
The 10 km north and 10 km south cancel out.
Only the 15 km westward movement remains.
So he is 15 km west of the school.
