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?

Q1 - Would it be 3hrs 10mins (allowing for the length of the goods train?
Q2 - just a tick.

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

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?
