Correct Answer: 12 km
Solution : Two men walk at speeds of 9 km/hr and 12 km/hr, respectively. Let the distance be $x$. Time taken to cover the distance by the first person = $\frac{x}{9}$ Time taken to cover the distance by the second person = $\frac{x}{12}$ According to the question, $\frac{x}{9}- \frac{x}{12} =\frac{20}{60}$ $ ⇒\frac{4x- 3x}{36} = \frac{20}{60}$ $⇒\frac{x}{36}=\frac{20}{60}$ $\therefore x = 12$ km Hence, the correct answer is 12 km.
