Answer:
3.5 m
Explanation:
The wording at the end is not very clear, but I am pretty sure that the question is asking for the total distance moved from the starting point. If this is the case, the answer is found by subtracting the two vectors from each other because they are in opposite directions. This gives you 3.5 m. If the question was asking for the actual total distance moved, you would just add them together and get 14.3 m, but I don't think that is what the question is asking for. Hope this helps! :)
