I want to know the answer to the following question:
Richmond is located at what line of the James river?
All the background I'm provided with is that "Richmond is located at the fall line of the James River, 44 miles (71 km) west of Williamsburg, 66 miles (106 km) east of Charlottesville, and 98 miles (158 km) south of Washington, D.C.". Is that enough to answer the question?
