  1. $66\ km$
  2. $30\ km$
  3. $6\ km$
  4. $36\ km$

C Correct answer
Explanation

When moving in the same direction, the relative speed is the difference of the speeds: 18 - 15 = 3 km/hr. Distance = relative speed * time = 3 * 2 = 6 km.

AI explanation

When two objects move in the same direction, their relative speed is the difference of their speeds. Here, the relative speed is 18 km/hr minus 15 km/hr, which equals 3 km/hr. Multiplying this relative speed by the total time of 2 hours gives a distance of 6 km.
