• 46 km is the answer.
  reason:
  1st case:-
  the person goes in 48 minutes.
  as 40 km of 50kmph
  2nd case:
  the person goes 120 minutes.
  as he goes 70 km at 35kmph
  at last 12 minutes
  so as a total 180 minutes.
  180 minutes at 52kmph
  so distance is 156 km
  already covered 110 km
  so last part will be 46 km.
