1) 2kms/hr
2) 1km/hr
3) 3kms/hr
4) 5kms/hr
5) None of these

• the speed of Car ‘X’=385kms/7hr=55kms/hr
  the speed of car ‘Y’=715kms/13hr=55kms/hr
  the difference is 0km/hr
  so, the answer is 5)none of these

• Sx=385/7 = 55 kmph
  Sy=715/13 = 55 kmph
  difference= Sx- Sy =55 - 55 =0
  ans:: none of these.
