Maths Puzzle - Trains

Two trains start towards each other at the same time (10AM) from points A, B respectively that are 100 km apart. 1st train travels at 20kmph and the 2nd train at 10kmph. The trains do not stop inbetween. If it wasn't 1PM when the trains reach a point where the distance between them is 10km, what was the time?
