problem_description: Statement
  
  Takahashi is meeting up with Aoki.
  
  They have planned to meet at a place that is D meters away from Takahashi's
  house in T minutes from now.
  
  Takahashi will leave his house now and go straight to the place at a speed of
  S meters per minute.
  
  Will he arrive in time?
