I want to know the answer to the following question:
Starting in the center of Kathmandu, how many kilometers must one travel to reach Tribhuvan International Airport?
All the background I'm provided with is that "The main international airport serving Kathmandu and thus Nepal is the Tribhuvan International Airport, located about six kilometers (6 km (3.7 mi)) from the city centre.". Is that enough to answer the question?
Answer: yes
