Two boys enter a running escalator at the ground floor in a shopping mall and they do some fun on it. The first boy repeatedly follows p1 = 1 step up and then q2 = 2 steps down whereas the second boy repeatedly follows p2 = 2 steps up and then q2 = 1 step down. Both of them move relative to escalator with speed vr = 50 cm/s. If the first boy takes t1 = 250 s and the second boy takes t2 = 50s to reach the first floor, how fast is the escalator running?
