The answer is D, because the longest side length (7) is shorter than the two other side lengths (2 and 6).
Answer:

Step-by-step explanation:
<u>Distance between two points</u>




Substituting points into the distance formula and solving for d:




The correct answer is 70 MPH because when 50 and 70 are added together and divided by 2, you get 60.
