2.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
(1) `(T_(2)T_(1))/(T_(2)-T_(1)),`
(2) `(T_(2)T_(1))/(T_(2)+T_(1))`
(3) `(T_(2)T_(1))/(T_(1)-T_(2)),`
(4) `(T_(2)+T_(1))/(2)`
