A toy train crosses 210 and 122 m long tunnels in 25 and 17 seconds respectively. Find the length of train and speed of train.

• Let the length of train be x m.
  so,
  distance = speed * time
  
  x + 210 = s * 25-------(1)
  x + 122 = s * 17-------(2)
  
  by solving equation 1 and 2
  
  we get s = 11 m/s
  and x = 65 m

• let speed of the train be u m/s and length of train be x m.
  so,
  x+210=u*25----(1)
  x+122=u*17-----(2)
  divide equation 1 by equation 2
  x=65 m and u=11 m/s.
