Time & Distance...

The speed of a 100 m long running train A is 40 % more than the speed of another 180 m long train B running in the opposite directions. To find out the speed of train B, which of the information given in statements P and Q is/are sufficient?

P: The two trains cross each other in 6 seconds
Q: The difference between the speeds of the two trains was 26 kmph.

Two stations A and B are 110 km apart on a straight line. One train starts from A at 7 a.m. and travels towards B at 20 kmph. Another train starts from B at 8 a.m. and travels towards A at a speed of 25 kmph. At what time will they meet?
