8th grade algebra!!!? - model bridge plans

Haylee is the modeling of the motorway Mark Clark, a continuous girder bridge over the Cooper River in Charleston, South Carolina. Part of the rays are formed by triangles. Haylee plans for the bridge model with the following scale: 1 inch to 12 feet. If the height of the triangle in the real bridge is 40 meters, the height of the model is it?

Please answer this question and shows all the work. I work on the proportions, so I think it is suppossed to an extent that the real model or something. Thank you. :-)
