The Deep Dive

Immagina di avere una pezza di stoffa di 40 cm da tagliare in due parti: una lunga e una corta. Chiamiamo la parte corta "x" cm. La parte lunga, quindi, sarà "40 - x" cm. Secondo la condizione data, la parte lunga deve superare di 1 cm il doppio della parte corta. Quindi possiamo impostare l'equazione: 40 - x = 2x + 1. Risolvendo questa equazione, otteniamo x = 13 cm per la parte corta e 27 cm per la parte lunga. La parte corta misura 13 cm, mentre la parte lunga è di 27 cm. Voilà, il mistero è svelato!
