Express the given locations of the mall and the park through the coordinates of a cartesian plane.
Let the east be +x and west be -x. Let north be +y and south be -y. From the given, the coordinates which describes the location of the Frostburg Mall is (-3,-2). Similarly, the coordinates that describes the location of the Sojourner Truth Park is (4,5).
The distance between the points is calculated through the equation,
d = sqrt ((x₂ - x₁)² + (y₂ - y₁)²)
Substituting the known values of the cordinates,
d = sqrt ((4 -(-3))² + (5 -(-2))²)
d = 7√2 miles
d = 9.899 miles
ANSWER: 9.9 miles
