B Correct answer
Explanation

When moving in opposite directions, the relative speed is the sum of the two speeds: 3 + 5 = 8 km/hr. After 3 hours, the distance between them is 8 km/hr * 3 hrs = 24 km.

AI explanation

When moving in opposite directions, the relative speed is the sum of their speeds. The combined speed is 3 km/hr plus 5 km/hr, which equals 8 km/hr. Multiplying this by 3 hours gives 24 km, so the distance is 24 km.
