I want to know the answer to the following question:
How far is Nanjing from Shanghai, in miles?
All the background I'm provided with is that "The city is 300 kilometres (190 mi) west-northwest of Shanghai, 1,200 kilometres (750 mi) south-southeast of Beijing, and 1,400 kilometres (870 mi) east-northeast of Chongqing.". Is that enough to answer the question?
Answer: yes
