Answer 1

Answer:

Displacement is the shortest distance between the starting and the ending point. Take the starting point as the origin and determine his position as he moves on his bike. Alex moves 700 m North along the path AB, 300 m east along BC, 400 m north along CD. At point D, Alex has coordinates : 1100 m north and 300 m east.
