Question

Two boys, starting at the same point, walk-in opposite directions for x meters, turn right and walk another y meters, and turn right and walk another x meters. What is the distance between them?

Answer 1

2y meters

Explanation:

The first x meters are cancelled with the last x meters because after turning right two times they walk in the opposite direction that each of them started to walk.

The y meters each of them walk are also in the opposite direction, so given that each of them walked y meters, the distance between them is 2y meters.
