Answer / rayz
Eh lads??
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.....the lads who said 12km were right
and the rest are incorrect.
So its worked out for ye in simple terms here!

Answer / naveen prasad
60km/hr ie. 1 KM=1 Min
80km/hr ie. 1.33Km=1 min
18 km distance means 18 Mins of trains and 9 mins of one
side train.
shuttle has 9 mins to fly.
distance =time*speed
t=9 mins
s=1.33km/s
So, 9 * 1.33 =11.97
Approxymately 12km.

Answer / sabarish
distance travelled by bird = speed of bird * time taken
= 80 * ( 18 / 60 ) = 12 km

Answer / md.mehtab
i think
speed of train=60km/hr
distence=18km
time 1hr=60 min
final speed after crashes of two trains is=80
speed of shuttleis =bird flies speed*time
= (80*18/7)
=12km

Answer / rudhra murthy s.
60km/hr ie. 1 KM will take to cross 1 Min
80km/hr ir. 1.33 Kms will take to cross 1 min
18 km distance means 18 Mins gone after the Shuttle crossed.
So, 18 * 1.33 = 23.94 km
Therefore, The Shuttle crossed "23.94 km" when the trains
crashed.
