Answer:
c
Explanation:
The graph has a positive slope (it's increasing). SO the scenario has to be something increasing.
a matches but only for the first part where the speed s 0 at the stop sign then approaching a stoplight, it would slow down, so the graph would turn down at that point.
for b, air temperature doesn't increase over 24 hours, it goes up then goes down after the sun sets.
d, the walking home from school you would be getting closer with every step, so the graph would have a negative slope (slope down)
c. the runner is racing and adding more distance with time, except the flat part where time passed but they didn't add any more distance since they were on the ground. After they got up and continued to run, the graph still slopes up since the distance they are running is increasing.
