metro train starts from rest and in five seconds achieves a speed 108 km/h. After that it moves with constant velocity and comes to rest after travelling 45m with uniform retardation. If total distance travelled is 395 m, find total time of travelling.

An automobile starts from rest and accelerates unifomly for 30 second to a speed of 72 km h^(-1) . It then moves with a uniform veocit and it is finally brought to rest in 50 m with a constant retardation.
