Above is a map from the winter of 1775, during the American Revolution. Using the scale on the map, what is the approximate distance between the British Landing on August 25th and the Battle of Brandywine on September 11th?

There is no map but my research shows that The Battle of Brandywine, also known as the Battle of Brandywine Creek, was fought between the American army of General George Washington and the British army of General Sir William Howe on September 11, 1777.
