Two friends X and Y start running and they run together for 50 m in the same direction and reach a point. X turns right and runs 60 m, while Y turns left and runs 40m. Then X turns left and runs 50m and stops, while Y turns right and runs 50 m and then stops. How far are the two friends from each other now?

Considering the turning point as the starting point and both facing north, we ignore the initial 50 meters.

X moves 60 meters East and then 50 meters South, while Y moves 40 meters West and then 50 meters South.

We calculate the distance by only considering the horizontal movement, which is 60 meters (East) + 40 meters (West). The 50 meters South can be ignored as it is common for both paths, having been already accounted for in the initial position.
