A and B are two stations 390 km apart. A train starts from A at 10 a.m. and travels towards B at 65 kmph. Another train starts from B at 11 a.m. and travels towards A at 35 kmph. At what time do they meet?
Choose the correct answer
A) 2.15 p.m.	B) 1.15 p.m.	C) 4.15 p.m.	D) 3.15 p.m.	E) 12.15 p.m.
Suppose they meet x hours after 10 a.m.   Then, (Distance moved by first in x hrs) + [Distance moved by second in (x-1) hrs]=390.   65x + 35(x-1) = 390 =&gt; 100x = 425 =&gt; x =	17/4   So, they meet 4 hrs.15 min. after 10 a.m i.e., at 2.15 p.m.   Option 2.15 p.m.
