Answer:
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
