A car traveling at 23 mi/h accelerates to 46 mi/h in 5 seconds. It maintains that speed for 5 seconds and then slows to a stop in 5 seconds. Which graph shows the car’s speed over time?
A. A number of points are shown on a graph. The points are connected by line segments.The y-axis is labeled Speed left-parenthesis miles per hour right-parenthesis and is numbered from 0 to 60 with a step size of 10. The x-axis is labeled Time left-parenthesis s right-parenthesis and is numbered from 0 to 15 with a step size of 5. The line segments connect these approximate points: left-parenthesis 0 comma 22 right-parenthesis and go through approximately left-parenthesis 5 comma 22 right-parenthesis, left-parenthesis 10 comma 46 right-parenthesis, and left-parenthesis 15 comma 46 right-parenthesis.
B. A number of points are shown on a graph. The points are connected by line segments.The y-axis is labeled Speed left-parenthesis miles per hour right-parenthesis and is numbered from 0 to 60 with a step size of 10. The x-axis is labeled Time left-parenthesis s right-parenthesis and is numbered from 0 to 15 with a step size of 5. The line segments connect these approximate points: left-parenthesis 0 comma 46 right-parenthesis and go through approximately left-parenthesis 5 comma 22 right-parenthesis, left-parenthesis 10 comma 22 right-parenthesis, and left-parenthesis 15 comma 0 right-parenthesis.
C. A number of points are shown on a graph. The points are connected by line segments.The y-axis is labeled Speed left-parenthesis miles per hour right-parenthesis and is numbered from 0 to 60 with a step size of 10. The x-axis is labeled Time left-parenthesis s right-parenthesis and is numbered from 0 to 15 with a step size of 5. The line segments connect these approximate points: left-parenthesis 0 comma 24 right-parenthesis and go through approximately left-parenthesis 5 comma 46 right-parenthesis, left-parenthesis 10 comma 46 right-parenthesis, and left-parenthesis 15 comma 0 right-parenthesis.
D. A number of points are shown on a graph. The points are connected by line segments.
