Hey!
Firstly We have to understand the Distance between Both the trains When A train started from A for B
B train started 20 min earlier. So distance covered by B in 1st 20 Min= 20*20/60
=20/3 KM
So Now distance Between both train when A started
= 450- 20/3
=1330/3 KMs
Now both train moving in the same direction. So Relative speed is= sum of speed of 2 vehicles or trains running in opposite direction!
So Relative Speed=15+20
=35 KM/hr
So Time Taken When They Meet= 1330/3*35
= 12⅔ Hours..
So distance Travelled by train A( Distance from Point A) = 15*12⅔
=190 KMs..
So Distance from A is 190 KMs...
I hope it Helps!
