Question

HELP MEEEEE PLZZZZZZZZZZZZZZZZZZZZZZZZ
Marc left his house to drive to work. He slowly pulls out of his driveway at a constant speed and continues at that speed until he slows and comes to a complete stop at the stop sign at the end of his street. He waits at the stop sign until it is his turn to go, and then his speed steadily increases until he reaches the speed limit. He drives at this constant speed until he approaches his office. He slows down steadily and comes to a complete stop in front of his office.



Which graph represents Marc’s drive to work?

Answer 1

The third graph. He stops twice, once at the stop sign and again when he reached his destination. on the graph this would be represented with the line at zero which means it can't be the first graph. since it says that he started at a constant speed that means the line doesn't start at zero (since zero indicates no movement and a diagonal line indicates acceleration and he did not accelerate to that speed he started at that speed) and the only other graph that doesn't start at zero is the third graph. This graph follows the journey described as it goes to zero for when he stopped at the stop sign and then accelerates up to the constant speed (the horizontal line) and the decelerates to a stop when he reached work (at the zero).

Answer 2

3rd graph is the correct answer
