Answer:
330 miles
Explanation:
The distance formula can be used to find the number of grid units between points.
d = √((x2 -x1)^2 +(y2 -y1)^2)
AC = √((-2-11)^2 +(6-(-2))^2) = √((-13)^2 +8^2) = √(169+64) = √233 ≈ 15.264
CD = √((-8-(-2))^2 +(9-6)^2) = √((-6)^2 +3^2) = √(36 +9) = √45 ≈ 6.708
Then the total distance in miles is ...
(15.264 units +6.708 unit)(15 miles/unit) ≈ 329.59 miles
Rounded to the nearest mile, the distance is 330 air miles.
