NOTE: I'm assuming this question is saying the passenger train catches the freight train 3 hours after the passenger train leaves. (NOT 3 hours after the freight train leaves.) That's what I'm basing the math on.
Passenger train:
Distance = 3r
Rate = r
Time = 3
Freight train:
Distance = 5(r - 10) = 5r - 50
Rate = r - 10
Time = 5
5r - 50 = 3r
2r = 50
r = 25
Passenger train:
Rate = r = 25
Freight train:
Rate = r - 10 = 25 - 10 = 15
