A person takes `T_(1)` second on the stationary escalator to cover some distance.The person takes `T_(2)` second in the moving escalator to cover same distance by same velocity.If person is at rest on the escalator then time taken by him to cover same distance is

A swimmer takes 4 second in crossing some distance in downstream and taken 6 second in upstream for same distance then find the time taken by him to cover same distance in still water.

A boat takes 4 hr upstream and 2 hr down the stream for covering the same distance. The ratio of velocity of boat to the water in river is

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 person walks up a stationary escalator in t_(1) second. If he remains stationary on the escalator. Then it can take him up in t_(2) swcond. If the length of the escalator is L , then a. Determine the speed of man with with respect to the escalator. b. Derermine the speed of the escalator. How much time would take him to walk up the moving escaltor?.

A motorboat covers a given distance in 6h moving downstream on a river. It covers the same distance in 10h moving upstream. The time it takes to cover the same distance in still water is

A boat takes 4 hrs to travel certain distance in a river in down stream and it takes 6 hrs to travel the same distance in upstream. Then the time taken by the boat to travel the same distance in still water is

A train travels a distance of 300 km with an average speed of 60 km h^(-1) . How much time does it take to cover the distance ?

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 :
