137.1kms....and 2.285hrs

suppose Mr A and Bee are in left side...
Now , They srart to travel
After, 1.714 hrs Bee and Mrs A meet and Bee travel 102.86 km and Mrs A travel 17.14 km and same time Mr A travel left to right is 51.429 km ...
So, We are taking 102.86 km which is travel by Bee...

Now, Distance between Mr A and See is 51.429 km...and they are now opposite to each other....
so they meet after 0.5714 hrs ...

So, Total time is 1.714hrs and 0.5714 is 2.285 hrs...

137.1 kms

I second Divya Murugesh but the case will be Mr and Mrs A are opposite to each other at same point and all three Mr A, Mrs A and Bee started moving from there with respective speed making distance of 120km between Mr A and Mrs A. Then, equation will be 30X+10X =120.
