Solve the Problem $y=-2.5 x+15(0<x<6)$ , Where $x$ Is the Number of Hours Paddled And

Multiple Choice

Solve the problem.
-Suppose that the speed at which an experienced person can paddle a canoe upstream is approximated by $y=-2.5 x+15(0<x<6)$ , where $x$ is the number of hours paddled and $y$ is the speed of the canoe in miles per hour. A portion of the graph of this equation is shown on the accompanying screen, along with the coordinates of a point on the line. How can this point be interpreted in the context of the model?

A) It means that after 7.5 hours of paddling, the canoe is traveling at a speed of 3 miles per hour.
B) It means that after 3 hours of paddling, the canoe is traveling at a speed of 7.5 miles per hour.
C) It means that an experienced person can paddle between 3 and 7.5 hours.
D) It means that the canoe can travel at a speed of between 3 and 7.5 miles per hour
