Ans.- B
Speed of car = 720/9 = 80 km/h
Speed of bus = 3/4 * 80 = 60 km/h
Speed of train = 27/15 * 60 = 108 km/h
Distance covered by train in 7 h = 108 * 7 = 756 km.
Speed of car = 720/9 = 80 km/h
Speed of bus = 3/4 * 80 = 60 km/h
Speed of train = 27/15 * 60 = 108 km/h
Distance covered by train in 7 h = 108 * 7 = 756 km.
