B Correct answer
Explanation

Since they are running in the same direction, their relative speed is the difference of their speeds, which is 3 - 2 = 1 km/hr. In 10 minutes (which is 1/6 of an hour), the distance between them will be 1 km/hr * 1/6 hr = 1/6 km, which is approximately 166.67 meters.

AI explanation

The relative speed moving in the same direction is 3 km/hr minus 2 km/hr, which is 1 km/hr. Converting this to meters per minute gives 1000 meters divided by 60, or 16.67 meters per minute. Multiplying by 10 minutes yields a distance of 166.67 m.
