A man traveled a total distance of 1200 km. He traveled one-third of the whole trip by plane and the distance traveled by train is two-thirds of the distance traveled by bus. If he traveled by train, plane and bus, how many kilometers did he travel by bus? Options:
A) 400  B) 440  C) 480  D) 520  E) 560
total distance traveled = 1200 km.   distance traveled by plane = 400 km.   distance traveled by bus = x   distance traveled by train = 2x/3   x + 2x/3 + 400 = 1200   5x/3 = 800   x = 480 km   The answer is 480.
