A cable, 16 meters in length, hangs between two pillars that are both 15 meters high. The ends of the cable are attached to the tops of the pillars. At its lowest point, the cable hangs 7 meters above the ground. How far are the two pillars apart?

Answers:

Answer #1
Note that it is a kind of trick question: the pillars stand next to each other. Which means that the cable goes 8 meters straight down and 8 meters straight up. Conclusion: The distance between the pillars is zero meters..

Answer #2
If the lowest point of the cable is 7 metre above the ground which means 8 metre from the top of the poll and thus the distance between them is zero as it is 8 metre down from each pole and thus it reaches its length which is 16 metres.8+8=16 which means cable is not left
