Problemas de Relojes. Ejemplos Históricos y Consideraciones Didácticas/Clock problems. Historical Examples and Didactical Considerations

The authors approach a classical Mathematical problem of computing the time passed, from a given moment, until the hands of a clock reach certain position. In particular, they focus on the case when the required position is the superposition of both hands. In this paper, they present some examples from classic and nineteenth century texts presenting different contexts where the problem arises as well as different solving methods. In addition, and as a consequence of this analysis, they present some didactical considerations that motivate the use of these resources with prospective teachers.
