Two stations A and B are 245 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?	Select the correct option
A) 9  B) 10  C) 11  D) 12  E) 1
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.   Therefore 20x + 25(x - 1) = 245   45x = 270   x = 6.   So, they meet at 1 p.m.   Answer: Option 1
