problem_description: Statement
  
  In order to pass the entrance examination tomorrow, Taro has to study for T
  more hours.
  
  Fortunately, he can _leap_ to World B where time passes X times as fast as it
  does in our world (World A).
  
  While (X \times t) hours pass in World B, t hours pass in World A.
