A blue print of a shopping complex shows that the bottom edge of the roof to be 93 feet above the ground. If the roof rises to a point 171 feet above the ground over a horizontal distance of 6.5 yards, what is the slope of the roof?

I am positive the answer is twelve, but the book is telling me the answer is 4! Who is right, and if the book is, what did I do wrong?
