Grade nine math algebra word problem.?

At 1:49PM the train was at 240.43 KM away from where it left, and the plain at 240KM from where it left. At 1:50 PM the train was at 242.09KM away from where it left and the plane at 245KM from where it left, so between 1:49PM and 1:50PM the plane overtaked the train, and it took 4 hour and 50 minutes for the plane to catch up and p the train, hope it helps.
