What is the direct distance (not walking distance, which would have to account for bridges and roadways) between the two landmarks in miles?

Your itinerary contains a grid map of New York, with each unit on the grid representing 0.25 miles. If the Rockefeller Center is located at (2,−1) and Central Park is located at (7,−6), what is the direct distance (not walking distance, which would have to account for bridges and roadways) between the two landmarks in miles? Round your answer to two decimal places, if necessary.
