A train having 15 bogies develops a technical snag in the carriage connecting its 5^th and 6^th bogies from the engine (i.e. front). The guard at the rear (i.e. the last bogie) notices the snag and immediately starts running towards it at a speed of 14 mps on the top of the roof. After some time, the driver’s assistant notices the fire and starts running towards it on the top of the roof at a speed of 10 mps. The length of each bogie is 35 m and the distance between any two bogies is negligible. If the train is running at a speed of 16 mps, how much time after the guard did the assistant notice the snag, if it is known that both of them reached the snag at the same time.
