I want to know the answer to the following question:
How many kilometers is it away from London?
All the background I'm provided with is that "By road it is 450 kilometres (280 mi) south-east of London, 287 kilometres (178 mi) south of Calais, 305 kilometres (190 mi) south-west of Brussels, 774 kilometres (481 mi) north of Marseille, 385 kilometres (239 mi) north-east of Nantes, and 135 kilometres (84 mi) south-east of Rouen.". Is that enough to answer the question?
Answer: yes
