Arjay and Dorothy live 2 miles from each other.
Dorothy and Melissa live 5 miles from each other.
Melissa and Gray live 3 miles from each other.
Arjay and Gray live 10 miles from each other.
How far do Dorothy and Gray live from each other

Answer 1

Dorothy and Gray live 8 miles apart.

Explanation:

With the limited nature of the question, we can assume they all live on a straight lime from one another or that the required distance between their houses to be obtained from this limited information isn't the shortest straight line distance between each and every house.

Dorothy and Melissa live 5 miles from each other.

Melissa and Gray live 3 miles from each other.

This means that, the distance between Dorothy and Gray is the sum of the distance between Dorothy & Melissa and Melissa & Gray = 5 + 3 = 8 miles.

Hope this Helps!!!
