escalator math - Alierak

I can walk up the long escalator without straining myself, but if I walk up the second escalator to ground level as well, I start to get winded.
One day recently, all the long escalators were working and I walked all the way up, but the second level up escalator was broken and I had to walk the stairs. That was painful.
