Answer:
Explanation:
Point A , P1 ( 11,-2) in the form (x1,y1)
Point D, P2(-8,9) in the form (x2,y2)
find the distance ( use distance formula )
d = sqrt [ (x2-x1)^2 +( y2-y1)^2 ]
d = sqrt [ (-8-11)^2 + ( 9-(-2))^2 ]
d = sqrt [ (-19)^2 + ( 9+2)^2 ]
d = sqrt [ 361 + ( 11)^2 ]
d = sqrt [ 361 + 121 ]
d = sqrt [ 482 ]
d = 21.8544
multiply that number by 15 for the miles
15*21.8544 = 329.317 miles
