Q:

A) 2:1 | B) 3:2 |

C) 4:3 | D) 5:4 |

Explanation:

Explanation:

Note : 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 = $\sqrt{9}:\sqrt{4}$ = 3 : 2
