Two trains started at the same time, one from A to B and the other from B to A . If they arrived at B and A respectively 4 hours and 9 hours after they passed each other the ratio of the speeds of the two trains was 

If two trains (or bodies) start at the same time from points A and B towards each other and after crossing they take a and b sec in reaching B and A respectively, then: (A's speed) : (B's speed) = (√b : √a)

Therefore, Ratio of the speeds of two trains =√ 9:√4 = 3 : 2

Hence, option 2 is the correct answer.
