Question 96770
If points A, B, and C lie on a coordinate line and points A and B
have coordinates 15 and 7 respectively, then which of the possible
coordinates for point C satisfy(ies) d(A, C) < d(B, C)?
----------------------
Draw a number line and mark two points as A=15, B=7
----
The midpoint between A and B is (15+7)/2 = 11
For d(A, C) < d(B, C) C must be close to A then to B
Darken the line between A and the midpoint.
C must be in that darkened piece of the line.
11<C<15
