C Correct answer
Explanation

Total distance = average speed × total time = 62 × 6 = 372 km. Train distance = 372 - 12 = 360 km. Train time = 360/120 = 3 hours. Walking time = 6 - 3 = 3 hours. Walking speed = 12/3 = 4 kmph. Ratio of walking speed to train speed = 4:120 = 1:30. The question tests understanding of average speed formula and weighted averages.
