I want to know the answer to the following question:
How far east of Chengdu is CETDZ?
All the background I'm provided with is that "Chengdu Economic and Technological Development Zone (CETDZ) lies 13.6 km (8.5 mi) east of Chengdu, the capital city of Sichuan Province and the hub of transportation and communication in southwest China.". Is that enough to answer the question?
