At the end of a snow storm, Riley saw there was a lot of snow on her front lawn. The temperature increased and the snow began to
melt at a steady rate. The depth of snow on Riley's lawn, in inches, can be modeled by the equation S = 13 – t, where t is the time, in hours, after the snow stopped falling. What is the x-intercept of the equation and what is its interpretation in the context of the problem?
