You think that statement is false?

rockinhood · Answer

Oh xD Forgot what the question was asking.

joannablackwelder · Answer

No worries, that's what I figured. :-)

rockinhood · Answer

C then? I think

joannablackwelder · Answer

No, distance is total distance traveled, and displacement is distance from the starting point.

joannablackwelder · Answer

For c, both of these values are 3.

joannablackwelder · Answer

3 km

These are a bit tricky. They take practice.
