The actual Question is :
Two trains at speed 60 km/hr comes in the opposite
direction. At a particular time the distance between the
two trains is 18km. A shuttle flies between the trains at
the speed of 80 km/hr. At the time the two trains crashes
what is the distance traveled by shuttle?

The two trains are 18km apart. Now we know both are
travelling at 60kmph so therefore they have a relative
speed of 120kmph...ie: they close on each other at 120kmph.

So as t=d/s
=18/120
= 0.15 hours

To get this in minutes....0.15x 0.6= 9 mins

So the question is how far can the shuttle go in 9 mins at
80kmph??

Well....d=s.t
=80x0.15
=12km.


So the answer is 12km
