Problem
Let 
be the intersection point of medians 
and 
of triangle 
if 
is 3 inches, then 
, in inches, is:
Solution
The fact that 
only tells us that 
. There are infinitely many triangles with a median which has length 9, so we can make no statement about the length of the median 
or the segment 
. Thus, is 
.
