select a graph for the situation. you leave home and head to a meeting you start out at a fairly steady pace until you get to pace until you get to a crosswalk. while stopped at the crosswalk you realize that you have forgotten your notes. you turn around and head back home at the same fairly steady pace. you grab your notes and then run to your meeting without stopping, although along the way your pace slows down a bit. the graphs show the amount of time that has passed and your distance from home

D

Step-by-step explanation:

A does not work, because you stop on the way to the meeting (which you don't)

B does not work, because you speed up on the way to the meeting, when in reality you slow down

C does not work, because it does not show that you went back home or changed speed at all
