The question is too vague: the Spanish Conquest of what? whom? The Aztecs? The Incas? Or do you mean the Re-conquest (La Reconquista), the winning back, after hundreds of years of Moorish occupation of Spain, by Christian Spain under the 'Reyes Catolicos', Ferdinand and Isabella? Be more specific, please.
It would be five years to defeat the Incas and the Mayas.
50 Years
The Incas all lived in South America. The Maya had been a culture in Central America but that culture had collapsed before the Spanish arrived. The Aztecs ruled Mexico. In the past few years there have been some discoveries that some trade might have existed between the Aztecs and the Incas. No indication has surfaced of any trade between the Incas and Central America.
