Um engenheiro deseja projetar uma ponte estaiada para ligar duas cidades vizinhas. Ele precisa instalar 8 cabos de sustentação que ligam uma torre (vertical) à parte horizontal da ponte, e dispõe de 1500 metros de cabo para isso. Os cabos devem ser fixados à mesma distância um do outro, tanto na torre quanto na parte horizontal. Assim, a distância da base da torre ao primeiro ponto de fixação vertical deve ser igual à distância entre dois pontos de fixação vertical consecutivos. Essa mesma distância deve ser utilizada da base da torre ao primeiro ponto de fixação horizontal e entre os pontos de fixação horizontal consecutivos, conforme mostra a figura a seguir:

Utilizando a aproximação 2–√≈1,41, determine, em metros, a distância aproximada entre dois pontos consecutivos de fixação desses cabos.
