How many centimeters is the distance between Nanjing and Beijing on the 1:10000000 Scale Railway diagram? [train a and B depart from Nanjing and Beijing at the same time. Train a travels 70km per hour, while train B travels 80km per hour. Four hours later, the distance between the two trains is still 1 / 3 of the whole journey. On the 1:10000000 Scale Railway diagram, what is the distance between Nanjing and Beijing in centimeters?] Urgent It's urgent. Upload it before 10:00,
Distance from Beijing to Nanjing: (70 + 80) * 4 * 3 = 1800 km = 1.8 * 10 ^ 8 cm
Distance on Scale:
1.8 * 10 ^ 8 / 10000000 = 1.8 * 10 ^ 8 / 10 ^ 7 = 18cm
