A wire with a length of 60 meter is hanging between two high voltage pylons. The wire is connected to the pylons at a height of 50 meters.
The middle part of the wire is 20 meters above ground level. How far
are the high voltage pylons standing apart?
Solution
0 meter,
because the length of the wire is exactly enough to go down from one pylon to the lowest point (30 meter) and up again (30 meter).
