The Frost-Truth bus travels on a straight road from Frostburg Mall to Sojourner Truth Park. The mall is 3 miles west and 4 miles south of the City center. The park is 2 miles east and 2 miles north of the center. how far is it from the mall to the park to the nearest tenth of a mile?

We will see a coordinate system with the origin in the City center.
The coordinates of the Mall are (-3, -4).
The coordinates of the Park are: (2, 2).
We need to find the distance between (-3. -4) and (2, 2):
√[(2+3)^2 +(2+4)^2] = √(25+36) = √61 = 7.8 miles
The Mall is 7.8 miles far from the Park.
