Triangle PQR has vertices at P(2, 4), Q(3, 8) and R(5, 4). A similarity transformation maps PQR to ABC, whose vertices are A(2, 4), B(5.5, 18), and C(12.5, 4). What is the scale factor of the dilation in the similarity transformation?

What I would do is calculate the distance between P and Q and then calculate the distance between A and B.  Then I would put those two values in a fraction.  Can you try to do that?  Use the distance formula.
