1. The problem statement, all variables and given/known data Let P and Q be points with corresponding vectors p and q. a) show that the vector 1/2p+1/2q is the midpoint of the line segment joining P and Q b)Find a point that is one third of the distance from P to Q 2. Relevant equations No idea 3. The attempt at a solution I'm not really sure.. but if you were to consider P to be one unit vector and Q to be one unit vector then PQ would be 2 unit vectors??
