Let us say that the escalator moves at the rate of n steps per second. Let us also say A takes 1 step per second and B takes 3 steps per second. Case 1: When A is coming down A will take 50 seconds to complete 50 steps. In 50 seconds, escalator would have moved 50n steps. Total number of steps on the stationary escalator = 50 + 50n Case 2: When B is coming down B will take 25 seconds to complete 75 steps In 25 seconds, escalator would have moved 25n steps. Total number of steps on the stationary escalator = 75 + 25n Total number of steps on the stationary escalator is a constant => 50 + 50n = 75 + 25n => 25n = 25
