• A horse chases a pony 2 hours after the pony runs.
  Horse takes 3 hours to reach the pony
  distance cover by pony=distance cover by horse
  speed*time(pony)=speed*time(horse
  pony time=5hrs
  horse time=3hrs
  speed (pony)*5=81*3
  ans 48.6

• as pony is taking 2 hours more than the horse to cover the distance say x.....so the total time taken by horse to cover x distance is 3hrs where as by pony 5hrs(takin 2 hrs more)..since time=dist/time
  for horse
  3=x/81=>x=243
  now for pony
  speed=dist/time
  speed=243/5=>48.6....that is option(d)
