Need help finding the range! I'll do the work, I'm just confused on what to do.
What is the range in height from the tallest fountain to the shortest fountain? Round to the nearest foot.

These are my coordinates:
Motor A Vertex coordinates: (5.9375, 564.0625)
Motor B Vertex coordinates: (6.5625, 689.0625)
Motor C Vertex coordinates: (7.1875, 826.5625)

Do I use the x coordinates or the y coordinates? Also, do you know if I'm supposed to add up and divide by all three, or do I just add the first and last and divide by the two?
