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 — The answer is 15 km and in the west direction.
Explanation
★The answer is 15 km and in the west direction.
★The boy goes 10 km north, then turns left to go 15 km west, then turns left to go 10 km south.
★The 10 km north and the 10 km south cancel each other.
★So he ends up 15 km due west of the school.
★The distance from the school is therefore 15 km, to the west.
★The other options do not match this position.
★So the answer is 15 km and in the west direction.
