.
In what direction is the second train traveling?
.
If train 1 is traveling west and train 2 is traveling east,
they are separating at (60km/h+55km/h) 115 km/h
575+km%2F%28115km%2Fhr%29=5hours
.
If both trains are traveling west,
they are separating at (60km/h-55km/h) 5 km/hr
575km%2F%285km%2Fh%29=115hours
.
Other times would depend on the relative direction of the trains.
.
The only answer possible would be some time between 5 and 115 hours.
