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?A.9 a.m. B.10 a.m.C.10.30 a.m. D.11 a.m.

Suppose they meet x hours after 7 a.m.Distance covered by A in x hours = 20x km.Distance covered by B in (x - 1) hours = 25(x - 1) km.20x + 25(x - 1) = 11045x = 135x = 3.So, they meet at 10 a.m.
