B Correct answer
Explanation

If distance = d km each, time = d/30 + d/90 + d/6 = d/30 + d/90 + 15d/90 = 3d/90 + d/90 + 15d/90 = 19d/90 hours. Given time = 38 min = 19/30 hours, so 19d/90 = 19/30, thus d = 3. Total distance = 3d = 9 km. But question asks for total distance traveled, which is 3d = 9 km. However, option B says 3, which suggests d = 3 is the answer expected. The question likely asks for d (distance per segment), not total distance.
