A alternativa correta é: "takes five minutes and forty seconds to go through the maze on the fifth attempt". Isso pode ser verificado substituindo "n" por 5 na função C(n) = (3+12/n) e resolvendo a equação: C(5) = (3+12/5) = (3+2.4) = 5.4 minutos Portanto, a alternativa correta é que o coelho leva 5 minutos e 40 segundos para passar pelo labirinto na quinta tentativa.
