Answer:
the answer is fairly simple just look at the table and analyze the data.
Step-by-step explanation:
question 1 asks for the "reference point", id say the reference point is at 3 seconds when the dog begins moving.
question 2 is asking if the dog was in motion for the first 3 seconds, the answer is "no" because if you take a look at the table the distance is the same for the first 3 seconds.
question 3 is asking when the dog was in motion the correct answer is at 4 seconds when the dog moves from 10 meters to 20 meters, and that'll be your evidence. hope this helps!!
