Lisa, bree,and caleb are meeting at an amusement park. they each enter at a different gate. explain how the friends could calculate the point that is equidistant from all three gates.

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.

Step-by-step 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

a) 15/20 = 3/4

b) 12/20 = 3/5

c) 12/15 = 4/5

d) 10/15 = 2/3

So. It must be answer c).
