Question

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

Answer 1

Find the distance from (-5,-3) to (4,4)

Distance= Sqrt[(-5-4)^2+(-3-4)^2]=Sqrt(81+49)=
Sqrt(130).

Without a calculator handy, the square root of 130 will be more than 11 (because 11*11=121) and less than 12 (12*12=144) but a little closer to 11.
