Answer:
The displacement is <u>2500 m</u> towards west.
Step-by-step explanation:
Taking west as negative direction and east as positive direction.
Velocity of man jogging west = -2.5 m/s
Time he traveled towards west = 1,200 s
Displacement in west direction = 
Velocity of man jogging east = 1.0 m/s
Time he traveled towards east = 500 s
Displacement in west direction = 
Total displacement can be calculated by finding the sum of displacement.
Total displacement = 
Since, the resultant displacement is negative, so the displacement is 2500 m towards west.
