The distance from a point to point C is 1, and the distance from that same point to point B is 4. The point must be .

See below.

Step-by-step explanation:

Start with point C.  

                                                       C

<+++++++++++>

Now we plot a point 1 unit from point C and call it D. D can be on either side of C. Call the new points D1 and D2.

                                            D2      C       D1

<+++++++++++>

Point B is 4 units from points D1 and D2, and it can be to the right or to the left, so there are 4 possible positions for point B. Let's call the 4 possible positions of point B: B1, B2, B3, B4.

     B1                B3               D2      C       D1                 B2               B4
