I want to know the answer to the following question:
How many metres apart are 181st Street's two subway stations?
All the background I'm provided with is that "181st Street is served by two New York City Subway lines; there is a 181st Street station at Fort Washington Avenue on the IND Eighth Avenue Line (A trains) and a 181st Street station at St. Nicholas Avenue on the IRT Broadway – Seventh Avenue Line (1 trains).". Is that enough to answer the question?
Answer: no
