Answer:
Explanation:
distance walked
5000 + 3000 + 1000 = 9000 m
time taken to do the walk
9000 m / 1 m/s = 9000 s
magnitude of displacement during the walk
d = √((5000 - 1000)² + 3000²) = 5000 m
direction of displacement
θ = arctan(3000/4000) = 36.869897...°
velocity
v = d/t = 5000 m / 9000 s = 0.5556 m/s 36.87° N of E
