D Correct answer
Explanation

Since the ratio of speeds is 5:4, the distances covered in the same time are also in a 5:4 ratio. Let distance of police be 5x and thief be 4x. The initial gap is 2km, so 5x - 4x = 2km, meaning x = 2. Police distance = 5 * 2 = 10 km.

AI explanation

Using the concept of relative speed, the ratio of distances covered equals the ratio of speeds. Let the distance the police runs be D, so D divided by (D minus 2) equals 5 divided by 4. Solving this equation gives 4D equals 5D minus 10, meaning D equals 10. The result is 10 km.
