A passenger train travelled at an average speed of 72 km/h. A man on the passenger train observed a goods train, which was travelling at a speed of 54 km/h, in the on-coming direction. If the goods train passed him in 10 seconds, find the length of the goods train.

Is it possible to find the length of the passenger train as well in this situation?
