a dog takes 4 leaps for every 5 leaps of a hare but 3
leaps of a dog are equal to 4 leaps of the hare .compare
their speeds(.......... please give explanation....)
Answer Posted / jainachran
Ans is 16:15.
Given that 3 Leap of dog=4 Leap of hare (means they travel same distance)
3 Ld = 4 Lh
Initially they said that 4 leaps of dog are equal to 5 leaps of hare.
so, speed of Dog=(Distance of dog 4Ld)/time.
similarily,speed of hare = (distance of hare 5Lh)/time.
now compare speeds
Sd/Sh=[4Ld/t] / [5Lh/t]
we get Sd/Sh=4Ld/5Lh
where,Ld/Lh=4/3
Sd/Sh=16/15

Samuel is obviously a bad fisherman. During the past season, in which he and the five members of his team spent four months on a boat together off Dutch Harbor, AK, he caught fewer fish than any of his teammates. Which of the following, if true, most weakens the argument above? While fishing this past season, Samuel fell sick for a week and did not catch any fish during this time. Before becoming a fisherman, Samuel piloted a fishing boat whose members regularly caught record numbers of fish. Unlike the other fishermen on his boat, at the order of the captain, Samuel fished this past season with experimental bait. Two seasons ago, Samuel fished on another boat off Dutch Harbor and caught more fish than any other member of that boat.
