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
