Coordinate A (X=482, Y=81)
Coordinate B (X=485, Y=83)
Coordinate C (X=484, Y=85)
Coordinate D (X=486, Y=87)
Coordinate E (X=483, Y=88)
Coordinate F (X=486, Y=89)
Distance between A and B = 3.6 miles
Distance between A and C = 4.5 miles
Distance between A and D = 7.2 miles
1. What is the distance between A & E?
2. What is the distance between A & F?
3. What is the distance between B & D?
Apart from answering, please also explain the forumulas used for calculating the distances.
