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 / monk
let 3 leap of dog = x = 4 leap of hair
let time taken by dog to take three leaps be 't'
dog takes 4 leap for every 5 leap of hair
so for every one leap of dog hair take 5/4 leaps
hence time taken by hair to take 3 leaps = (4/5)*t
time taken by hair to take 4 leaps =(4/5)*(1/3)*4*t=(16/15)t
now
speed of dog'Vd'=x/t
speed of hair'Vh'=x*15/16t
hence Vd:Vh = 16:15
