A train is running at a speed of 40 km/hr and it crosses a post in 18 seconds. What is the length of the train?

• speed=(length/time)
  length=S*T
  L=(40000*18)/3600
  L=200metre...(km to m *by1000)and (hr into sec /by 3600)

• ANswer:200meters
  Speed of the train, v = 40 km/hr = 40000/3600 m/s = 400/36 m/s
  
  Time taken to cross, t = 18 s
  
  Distance Covered, d = vt = (400/36)× 18 = 200 m
  
  Distance covered is equal to the length of the train = 200 m
