Answer:
1. Displacement = 3.29 km
b. His direction is
north of east
2. Average velocity is 1.10 km/h
b. His direction is
north of east
3. Average speed = 1.52 km/h
Step-by-step explanation:
1. Displacement =

=

=

= 3.2867
Displacement = 3.29 km
b. tan θ =

θ =

=
0.6546
= 33.20878
θ =

His direction is
north of east
2. Average velocity =

=

= 1.09667
Average velocity is 1.10 km/h
b. His direction is
north of east.
3. average speed =

total distance covered = 1.80 km + 2.75 km
= 4.55 km
Average speed =

= 1.5167
Average speed = 1.52 km/h
