Final answer:
To determine the coordinates of the new hub after shipments from City A triple, add the vector representing the shipments to the coordinates of the existing hub.
Step-by-step explanation:
To determine the coordinates of the new hub after shipments from City A triple, we need the coordinates of the existing hub and the vector representing the shipments. Let's assume the coordinates of the existing hub are (x, y) and the vector representing the shipments is (a, b).
The coordinates of the new hub can be found by adding the vector to the existing hub coordinates: (x + 3a, y + 3b).
To calculate the suggested x-coordinate for the new central hub, we need to consider only the x-coordinate of the existing hub and multiply it by 3: x_new = 3x.
