Solve the problem.The graph depicts a person's speed y, in miles per hour, during a 15-minute period of driving. Estimate and interpret the turning points.
A. The first turning point is at approximately (6, 48). This is where the person's speed first stops increasing and starts to decrease. The second turning point is at approximately 
. This is where the person's speed stops decreasing and starts to increase again.
B. The first turning point is at approximately (7, 48). This is where the person's speed first stops increasing and starts to decrease. The second turning point is at approximately (11, 44). This is where the person's speed stops decreasing and starts to increase again.
C. The first turning point is at approximately (5, 48). This is where the person's distance from the starting point stops increasing and starts to decrease. The second turning point is at approximately (9, 44). This is where the person's distance from the starting point stops decreasing and starts to increase again.
