Can someone help? An environmental engineer graphed the locations of a well and all of the drainage ditches in the vicinity. She positioned the well at (−3,7) and the farthest drainage ditch at (36,7). If each unit on the graph represents 1 foot, then how far away from the well is the farthest drainage ditch?

Icould really use some with this question.
