The distance, y, in miles, traveled by a car in a certain amount of time, x, in hours, is shown in the graph below:



Which of the following best describes the motion of the car shown? (1 point)


It travels for 1 hour, then stops for 1 hour, and finally travels again for 3 hours.

It travels for 2 hours, then stops for 1 hour, and finally travels again for 2 hours.

It travels for 1 hour, then stops for 2 hours, and finally travels again for 5 hours.

It travels for 2 hours, then stops for 3 hours, and finally travels again for 5 hours.

Answer 1

Answer: Choice A. It travels for 1 hour, stops for 1 hour, then travels for 3 hours

------------------------------------------------

Any portion of the graph that isn't flat and horizontal is when the car is traveling. In this case, it's the portion from x = 0 to x = 1 (the first hour of travel) and the portion from x = 2 to x = 5 (the final three hours of travel). The flat portion starts at x = 1 and stops at x = 2. So this represents 1 hour of rest. This is where the distance (y) isn't changing.
