a freight train leaves a station traveling at 32 km/h. two hours later a passenger train leaves the same station traveling in the same direction at 52km.h.

Q1: How long does it take for the passenger train to catch up to the freight train?
Q2: How long does it take for the train to be cancelled?

3 hrs 12 mins if the clock starts when the passenger train leaves. Otherwise, 5 hrs 12 mins, and it is after 166.4 km

Hold ON!
Isn't this a place to ask questions? Questions you don't know the answer to? Are we expected to know the answer to the questions we ask, what would be the point in that?

Right - If a ball can bounce 3 times a day and a squirrel can eat 15 nuts an hour, how tall is the tale my grandfather used to tell?

I think that there are some occasions where a certain expectation is allowed? (No Dogs Aloud.)
