  The first train travels H hours
  
  The second train travels  one hour less  = H  -1
  
  And rate * time  = distance....so....
  
  50*H  + 70 * (H - 1)    =  350       simplify
  
  50H + 70H  - 70  = 350
  
  120H  - 70  =  350      add 70 to both sides
  
  120H  = 420             divide both sides  by 120
  
  H  = 420 /120   =  3.5 hrs
  
  So....they meet  at   3:30 PM
