Answer:
( 10 , 15 )
Step-by-step explanation:
If two points
form a line segment AB and is divided in the ratio of m:n by a point O(x, y). The coordinates of point O is calculated as follows:

Given Segment ST from S(−5 , 0 ) to T(20, 25 ) divided in a 3:2 ratio by point M. Let us assume the coordinates of M is at (x, y), then:

The coordinate of M is at (10, 15)
