6. A hare and a tortoise have a race along a circle of 100 yards diameter. The tortoise goes in one direction and the hare in the other. The hare starts after the tortoise has covered 1/5 of its distance and that too leisurely. The hare and tortoise meet when the hare has covered only 1/8 of the distance. By what factor should the hare increase its speed so as to tie the race? a. 8
37.80

ANS :37.80

• distance coverd by hourse =73*4=292
  total time taken by =3hr+4hr =7hr
  speed of pony =292/7 =41.71

• time taken by horse in 4 hours. since the pony left the stable 3 hours earlier, time taken by pony is 7 hrs. distance covered by both is same when the horse catches up with the pony. usin the formula time*speed=distance, we make equation 73*4=7x. thus speed of pony is 73*4/7=41.71

• i think ans for que 1 is 41.71
  bcoz the distance is same for bothe horses which is 73kmph*4hrs=292km
  now the pony has started 3 hrs before and travelled for a total of 7 hrs so 7*x=292
  x=292/7
  x=41.71

• c)41.71
  73*4=292km
  292/(3+4)=41.71
