A portion of a track for a roller coaster is supported by two beams of different heights.
The 40 foot and 30 foot beams are perpendicular to the ground.
Steel cables are attached from the top of one beam to the bottom of the other beam.
How far off the ground do the cables intersect?
:
This can be solved using the "product over sum" of the heights of the two beams
%2840%2A30%29%2F%2840%2B30%29 = 1200%2F70 = 17.143 feet off the ground at intersection
