Answer:
The answer is B
Please read the explanation... it always helps!!!
Explanation:
All of the choices ask for difference.... it really helps when you draw a number line to solve these types of questions....
but for B you will need to imagine a compass..
alrighty for option B lets examine why it is correct....
Imagine you were standing on a dot (lol)
you walked 1.5 steps to the left <--
then you walked 1.5 steps to the right -->
you can see that you walked in opposite directions and in the end you will be back where you started (aka on the dot, still lol)
meaning the displacement is zero
that is why option B is correct
i really hope this isn't confusing and it helps!!!
