A shopping mall has an escalator moving uniformly from the bottom to the top. Two people, A and B, are in a hurry to go upstairs for errands. While riding the escalator, they also climb the stairs at a uniform speed. Person A reaches the top after climbing 55 steps, and person B, whose climbing speed is twice that of A (B climbs twice as many steps as A in the same amount of time), reaches the top after climbing 60 steps. How many steps does the escalator have from the bottom to the top?
