A train of length 105 m takes 11 seconds to pass completely through a station of length 225 m. Calculate the speed in kilometer per hour (km per hr).

30 m/s

Step-by-step explanation:

Length of train; l = 105 m

Length of station; L = 225 m

Time to cross station; t = 11 s

Total distance the train will have to travel to cross the station = length of train + length of station = 105 + 225 = 330 m

Speed is given by the formula;

Speed = distance/time

Speed = 330/11 = 30 m/s
