Answer:
the 4th answer option
Step-by-step explanation:
the first one is looking good too, but the difference is to start at 4 meters away.
and the first graph starts at 9 meets away.
so, it is the 4th graph :
starting 4 meters away the person is coming slowly closer and closer for 8 seconds, then stands still for 3 seconds, and then walks away quickly for 4 seconds.
remember, the passing time is on the x-axis moving to the right (bigger and bigger numbers).
while the distance to the person is on the y-axis. and that value can get bigger and smaller.
