c = 30 kph
p = 60 kph
---
s = d / t
d = s * t
---
when the trains meet they are both at the same distance D from the station, but p has traveled 1 hour less than c
---
D = ct = p(t - 1)
ct = p(t - 1)
30t = 60(t - 1)
30t = 60t - 60
60 = 30t
---
t = 2
---
D = ct
D = 30*2
D = 60
---
Answer:
the trains meet when both trains are 60 km from the station
