two trains are coming in the opposite direction each at a speed of 60 kmph, now a fly on one train moves towards the other with a speed of 80kmph, how much distance will it cover before it is crushed.?

• It will depend on the initial distance between two trains which is not given here.

• 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
