At 8pm a freight train leaves town traveling at 200 km/hr. At 1am a passenger train leaves the same station traveling in the same direction, along the same route at 130 mph. How long will it take the passenger train to overtake the freight train? How far will they be from the station at this time?

Dude, it's not that hard, it's simple Algebra
rate * times = distance
rate(freight) * time(freight) = rate(passenger) * time(passenger)
Let x = time it takes for the trains to meet starting when the freight train started
200 * x = 209.21472 * (x - 5)
200x = 209.21472x - 046.0736
9.21472x = 1046.0736
x = 113.522017
It will take about 113 and a half hours for the passenger to overtake the freight.
They will be about 22704 km away from the station
