Answer 2

Given :

A train travelling at 55 kmph leaves Mumbai at 6 am .

Another train starts from Mumbai at 9 am in the same direction at the speed of 65 kmph .

To Find :

After how many km from Mumbai will the two trains be together .

Solution :

Let after time t from second train both the train meet .

Therefore , for first train time taken is 3 + t ( because it started three hours before ).

Therefore ,

$d_1=d_2\\55(t+3)=65t\\t=\dfrac{165}{10}\\\\t=16.5\ hr$

So , distance covered is ,

$D=65\times 16.5\\\\D=2722.5 \ km$
