Answer:
Correct Answer: A
Solution:
- If two persons starts at the same time from two points A and B towards each other and after crossing they take a and b hours in reaching B and A, respectively.
Then, $ \frac{A’s,speed}{B’s,speed}=\frac{\sqrt{b}}{\sqrt{a}} $
$ =\frac{\sqrt{9}}{\sqrt{4}}=\frac{3}{2}=3:2 $
