Answer:
By joining the entry point of all three friends to form a triangle and then finding the centroid of this triangle , they can calculate the required point.
Explanation:
STEP 1 : First join all the three entry points of the friends in order to form a triangle.
STEP 2 : Now we need to find the centroid of the triangle, so all three must start moving in the direction of the midpoint of the opposite side.
In this way, the point equidistant from all the three gates can be calculated
