Question 65943
On a map's coordinate grid, Panthersville is located at (-3,2), and Heel City is located at (4,8). Falconton is the midpoint between Panthersville and Heel City. What is the approximate distance from Panthersville to Falconton? (One map unit equals on mile).
-----------
Distance from Pather to Heel = sqrt[(4+3)^2+(8-2)^2]=sqrt(85)
=9.22 map units
Half that distance is 4.61 map units
Converting to miles you get 4.61 miles 
Cheers,
