the distance between two train stations is 30 km. a locomotive starting from one station gave the train an acceleration that made it reach 72km/h in 40seconds and this acceleration continued until the speed of the train reached 108km/h. This speed was maintained until brakes were applied to eventually bring the train to a stop at the second station under a uniform deceleration of 2m/s^2. How long did the entire journey take?β
