1. Rachel drove 300 miles from her home to Philadelphia to visit her
sister and then returned home a week later. At the end of the trip,
what was her displacement and distance traveled, in that order?

Johnny rode his bike to a friend's house 4 blocks down the street in his neighborhood. he immediately rode back home once he realized his friend was not able to play. what was his displacement for the total bike ride? how did you determine this? what could we use as a reference point to determine he was in motion during his bike ride? why can you use it as a reference point
