Answer Posted / ravi ranjan sinha
let x is distance from A to B
and y is initial speed.
30/y+(x-30)5/4y -x/y = 3/4
=>
4x-12y=120 ----(1).
45/y + (x-45)5/4y -x/y=3/5
=>
5x-12y=225 -------(2).
From equ (1) and equ (2) we will get.
x=25 and y=105
so initial speed is 25
and Distance From A to B is 105
Ans 25,105
