Preeti reached the metro station and found that the escalator was not working. She walked up the stationary escalator in time t_1 . On other days, if the remains stationary on the moving escalator, then the escalator takes her up in time t_2 . The time taken by her to walk up on the moving escalator will be :

A passenger is walking on an escalator at a speed of 6 km/h relative to the escalator. The escalator is moving at 3 km/h relative to ground and has a total length of 120 m. The time taken by him to reach the end of the escalator is

It takes one minute for a passenger standing on an escalator to reach the top. If the escalator does not move it takes him 3 minute to walk up. How long will it take for the passenger to arrive at the top if he walks up the moving escalator ?

A person walks up a stationary escalator in time t_(1) . If he remains stationary on the escalator, then it can take him up in time t_(2) . How much time would it take for him to walk up the moving escalator?

A man standing on a moving escalator, completes a certain distance in time t_(1) . If the escalator does not move then man covers this distance in time t_(2) by walking. (i) How much time will he take to cover the same distance if he move on the moving escalator in the same direction ? (ii) How much time will he take to cover the same distance if he move on the moving escalator in the opposite direction ?

A boy at the airport takes time t_1 to walk on escalator if the escalator is at rest and takes time t_2 if boy is at rest on moving escalator.Then find the time taken to walk on the escalator for same path?
