3. A pizza delivery person starts off at home which is 12.0 km south of the pizza restaurant. They move north to the restaurant (this takes 40.0 min) to pick up the pizzas (which takes 10.0 min), then move to a position 6.0 km north of the restaurant to make the rst delivery (which takes 25.0 min), then move from that last position 3.0 km south to make the second delivery (which takes 15.0 min), then they return to the pizza restaurant (15.0 min). a) Draw a scaled diagram of this movement which shows vectors for the initial and nal positions, each of the four displacements and the total overall displacement. b) Label each of the vectors with the appropriate symbols for the vector - not just with the measurements
