A train travels 480 km at uniform speed.If speed has been 8 kmph less,then it would taken 3 hrs more to cover the same distance.Find the speed of train

• Let,speed is S and time is T
  
  Given,
  Distance =480
  T=480/S
  
  If speed has been 8 kmph less,then it would taken 3 hrs more to cover the same distance, then
  T+3=480/(S-8)
  
  solve both equations,
  S=40 kmph
