Acar traveling at 46 mi/h slows to a speed of 23 mi/h in 5 seconds. it maintains that speed for 5 seconds and then slows to stop after 5 more seconds. which graph shows the car's speed overtime

You didn't include the graphs. However, I can describe the graph for you, so you can select the correct graph.

First, the car slows. So look for a line segment that is pointing down diagonally. Then, it maintains the speed. Look for a line that is horizontal. Finally, it slows down again to a stop. Look for a line segment that slants downward and touches the x axis.

B. 2 1/2 feet. multiply 2.5 inches by 12 to get thirty inches then divide by 12 to get 2.5 feet
