The total distance that Dominik will have to walk is the sum of the length of the escalator and the distance that the escalator has traveled. Let t be the time it will take him to reach the top of the escalator. The equation that best models the situation is,
                          225 ft + (82 ft/min) x t = (106 ft/min) x t
The value of t is 9.375 minutes.
