The athlet at point A runs 150m east, then 70m west and then 100 east Determine the resultant displacement of the athlete relative to point A

180m to the east

Explanation:

Displacement is the distance traveled in a specific direction. It is a vector quantity with both magnitude and direction. Therefore, the start and finish position is very paramount.

  point A runs 150m east,

   70m west

  100m east

                                       150m

                →

                                                                   70m

                                                         ←

                                                                   100m

                                                         →

The displacement of the athlete  = 150 - 80 + 100  = 180m to the east

i think the answer would be reserve.
