Problems on train using Quadratic Equations and Distance, Time and Speed by Grasp & Learn.

A goods train leaves a station at 5 p.m., followed by an express train which leaves at 7 p.m. and travels 20km/hour faster than the goods train. The express train arrives at a station, 1040 km away, 36 minutes before the goods train. Assuming that the speeds of both the trains remain constant between the two stations; calculate their speeds.

Question from 10th ICSE board. Solved very easily and explained using animations.
